Why doesn't my server crash....

[pklloveyou]

1. ChatStrictLinkChecking.Severity = 0
   
2. ChatStrictLinkChecking.Severity = 3
   
   No display after sending

I don't know, my server crash, be sure that your server is loading the right worldserver.conf with severity = 3.

@avatar789 tested too and got the same results.

I use this script, nothing else:

/run function CrashServer() SendChatMessage("\124cffffd000\124Henchant:59387\124h[Inscription]\124h\124r", "SAY") end CrashServer()

Tested and my Server crashed after executing the script with a level 1 player character (commit: fae7ae9).

[LichKing255]

Why doesn't my server crash....

1. ChatStrictLinkChecking

change ChatFakeMessagePreventing from 0 to 1.

[Helias]

I have ChatFakeMessagePreventing = 0 and the server still crashes when I put severity=3.

Fixed, you can test the PR :wink:
