Issue / Bug

End Dragon does not spawn when entering the end.

Expected Behavior

End dragon should spawn

Make some way to get end crystals to vanilla spawn it/find conflict causing the issue.

Go to the end via end portal in stronghold.

Cannot reproduce. I've had no problem getting him to spawn when testing this out.

[Darkosto]

Just opened an instance up and went to the end:

[zahlost]

I'm having the same issue. I went to the end but no ender dragon spawned. Ores have not spawned. The only hostile mobs that populate the end are enderman and abyssal zombies.

• Minecraft version: 1.12.2 (modded) forge-14.23.2.2651
• Modpack version: 3.0.5
• Latest java
• Twitch launcher
• SP
• No resourcepack

Update: Thanks Flickofdawrist, that did fix it for me as well.

[Flickofdawrist]

Same problem with latest 3.0.6 modpack version. World was created on 3.0.4 and I just got to end and there is no dragon.

Update: For some reason my level.dat file had DragonKilled 1 before I even entered the dimension. I manually set it back to zero and deleted the end dimension world folder (DIM1) to fix it.

I am also getting the same issue with the end not spawning the dragon.

[futileohm]

The end dragon didn't spawn for me either. I also had DragonKilled (and PreviouslyKilled) set to 1 in the NBT data despite never having been to the end before.

[Dystilled]

A number of people in the discord have also confirmed this as an issue.

Is there any chance it's to do with naturally spawning portals rather than creatived in ones? Dunno if thats possible

[Dystilled]

Yep, my DragonKilled and PreviouslyKilled was also set to 1... Something odd there.

As a note, I changed the value and didn't need to delete my nether.

[unclesamx]

I got my own dedicated server and got the same problem. I manually spawned the enderdragon in and the ores appeared but there's no End portal/portal to the end cities. The achievement also doesn't trigger. How can I solve this on a server?

[justinrusso]

@harmjan94 likely the same way other users have stated. Editing the level.dat file and setting DragonKilled to 0

[unclesamx]

In my server files?

edit: because I already did on my local files

[justinrusso]

Also, if you read the advancement, it states that you need to mine the Biotite and then create Ender Alloy.

[mckibbon17]

Flickofdawrist has the fix for it you will have to do what he said with the server files edit the values delete that dim and go back in and it will be spawned

[Deadnoz]

@darkosto recreating it from the wrong age doesnt mean its unreproducible. because alot of our dragon kill counts were at 1. It means one of the ages was moving it to 1, and what you discovered is it wasnt the tutorial age.

[justinrusso]

@Deadnoz I'm in the world with all stages and all advancements and it works fine. Stages, nor any advancement, triggers that change.

[Deadnoz]

@justinrusso considering this thread has a small few, and a lot of people in streams are curious about the issue, Just because you are fine, doesn't mean the issue is resolved sadly. Besides that, darkosto replied in stream and i understand it a bit more.

[justinrusso]

@Deadnoz Im not sure what youre going on about. Neither I or Darkosto have said this issue is resolved. It would be closed if so.

[Muddr]

Be interesting to see what versions the worlds were created in, that are having the issue. Mine is from 3.0.0 (MP moved later to SP) and I have both DragonKilled and PreviouslyKilled set to 1.

I copied the world and jumped into stage 4 and went to the end and no dragon spawned. Doing Save and Quit while in the end and then coming back into the world will show the boss bar for a second and then it goes away. I did /gchouston back to the overworld, left, and then set DragonKilled and PreviouslyKilled to 0. went back to the end and the dragon was there.

I tried creating a 3.0.6 world and giving myself items to follow the advancements to where I'm at a now (going into dimensions, killing bosses, etc) and I can't reproduce it (DragonKilled and PreviouslyKilled are never even set). So might have been a side effect of an old version.

[Dystilled]

My world was from the day of release.

[DerpityDoo]

My world was created in 3.0.1 and also had DragonKilled and PreviouslyKilled set to 1. Perhaps this was fixed in a later update unknowingly. Would be worth installing a few different versions of the pack to see if this is the case.

[sarcastic6]

I think you guys might be barking up the wrong tree with this DragonKilled/PreviouslyKilled thing:

• Create a new Minecraft instance and install Forge and only Forge.
• Create a world, quit before you go to The End.
• Examine level.dat, you'll see that DragonKilled and PreviouslyKilled are both 1.
• Travel to The End, notice that the dragon does in fact spawn
• Re-examine level.dat, and you'll see that DragonKilled and PreviouslyKilled are now both set to 0.

Based on the above, I don't think the fact that those values are 1 if you've never been to The End has any significance.

[Dystilled]

However, setting those settings to zero fixes the issue.

If what you've posted is correct, what it indicates to me is that entering the end for the first time is supposed to trigger a reset of the values from 1 to 0 to spawn the dragon, but something is preventing that.

[benstrathdee]

Just to add to the data here, I also experienced the issue

Modpack Version: 3.0.6
Java Version: 161 64bit
Launcher Used: Twitch launching Jar launcher
Server/LAN/Single Player: SP, opened to LAN a few times, but no other players
World created in 3.0.0

Interestingly, saving + quitting while in The End and reloading the world (not closing the game completely though), causes the End Dragon's Boss Bar to appear on screen briefly upon load, but it disappears shortly afterwards.
Ultimately I used NBTExplorer to set both DragonKilled and PreviouslyKilled to 0 (were set to 1 as others had noted). I did not need to delete any Dimension data, after loading the world again (still in The End) the Dragon was now present.

[Rixxaw]

Button just had it happen on his stream. Maybe one of the boss mobs that we kill along the way is setting dragon kill to 1 ?

[witzatom]

I have ran into this issue aswell. Played this pack since 3.0.3 and now at 3.0.6 when I arrived into the End the Dragon does not spawn.

[DaedalusGame]

Heyo, we had a poke at the relevant code and I think this is caused by a mod loading the End, then immediently unloading it before the world can tick once. I'm not sure which mod would do that, but chunk pregeneration thingies are a good shot. I'm trying to wrap my head around the dragon fight code right now to see if i can get some proper data

Yeah this is actually a forge issue. So uh... downgrade forge I guess? Or wait for the inevitable fix. Or just don't pregen. Shoutout to quadraxis (bs2609 on github) for tipping me off rofl.

[Jandakast]

This is in fact a Forge issue. Any worlds created in Vanilla 1.12.2 or prior to Forge 2647 have the dragonKilled and previouslyKilled flags set to true which cause the changes made in Forge 2651 for dimensional teleportation to incorrectly ignore the scanForLegacyFight flag. This makes the game think the Ender Dragon has already been killed and does not spawn the Dragon or the Portal Frame.

There is a Pull request in to forge that should address this issue.
https://github.com/MinecraftForge/MinecraftForge/pull/4868

The Fix, as @DaedalusGame mentioned, would be to roll Forge back to 2650 until Forge releases a version that incorporates the fix.

[mezz]

This has been fixed in Forge 1.12.2 - 14.23.3.2666

[DaedalusGame]

666 oh boy...

[MrHrulgin]

For anyone following this saga, despite this problem being fixed in Forge 1.12.2 - 14.23.3.2666, attempting to use that version will cause an immediate crash upon starting minecraft using SevTech 3.0.6. For me, sitting in the End without an Ender Dragon, rolling Forge back to 2650 worked perfectly, and an ender dragon appeared as soon as I opened the game back up.

[Syltann]

Same issue..

[tjsd]

3.0.6 is not compatible with higher forge versions because of other mods. This will be fixed in 3.0.7

[Possemaster]

I have the exact same issue on 3.0.6, we just entered the End for the first time. And the dragon does not spawn.

[Darkosto]

Locking this post. The answer has already been given and comments after this point are not needed.
