By chance do you know about how big of an area you searched?
Well, this is going to be a two-fold question:
Would be good to have confirmation from someone who is seeing these in a Venus newly generated after build 142?
Spectator Mode (/gamemode 3) should help you to find Sulfuric Acid pockets easily.
@EzerArch: structures in Galacticraft are the Dungeons and the Abandoned Base. I think those must be affected by that flag.
Vapour Spout, Crashed Probe and other smaller terrain features are not affected by "Generate Structures".
thank you nice before and after images
that should help to narrow it down
Spouts/Acid are fine on 1.10.2 and 1.11.2, but they are broken on 1.12.2
thank you, I'll check 1.12.2 - thank you for saving me time
Guys thank you for these careful reports. I've found the problem, fixed in next build 144. 72f414b
Unfortunately, this will have affected - like @FrostQ says - all 1.12.2 versions from builds 132 to 143. This is a big shame, because any player who has already generated Venus in those versions will be missing the features, until they go to new chunks.
Deleting DIM-31 is probably the only option, and let it regenerate in build 144. (There is no easy way to retrogen chunks, at least not without risk of damaging player builds.)
I'm very sorry about this. I didn't notice anything missing because my main 1.12.2 test games both already have a lot of the map on Venus generated. And on a new game, there is nothing "obviously" wrong - the surface and landscape of Venus still looks OK.
I could make a chunk worldgen reset wand item for server owners to use in-game - have thought about that for dealing with a few other situations too - but it would take me a lot of time and I think my time is better spent on Galacticraft proper. There must be other Minecraft server tools or plugins which can do this already?
(In the old ICBM mod there used to be the Rejuvenation Explosive although - like a lot in ICBM - that was badly coded and crash-prone on servers.)
Personally i wouldnt worry about it to much it will slowly get better aa people start exploring or start new worlds or/and reset servers thankfully its not a fully needed world gen resource like dungeons.
It was the same with the eggs on mars not generating

There's a trick solution if someone wants to try: install MCEdit, open your world save, delete existing chunks (not those where you have built something on), save, reopen world save on Minecraft to regenerate chunks. As always, back up your precious world!
