nwserver 1.69 unpatched
nwnx-2.7-beta2
functions 1.8.1
events 1.1.5
odbc waawaa
chat 0.3.2 <- culprit

Happens as soon as a player logs in, selects a character and clicks the Ok/Login-Button.

Remove the chat plugin, and the whole thing works again. The other plugins do not seem to affect this behaviour. Same reaction only running nwnx2 + chat.

Haven't had time to investigate if it is module-specific (im running a 60mb+ mod with a heapload of nwnx-centric self-developed scripts).

Hey! Where did you get a time machine? Laughing

Thanks for the bug report. Can you make a core dump and send it to my email?

Sure. It'll take a day or two, though.

if you try to get the message text twice, it will probably crash

virusman_ru, 11:21:58:
and it crashes if you pass the wrong parameter to GetPlayerID

virusman_ru, 11:22:10:
0 or empty string

I made an 'unofficial' 0.3.3 version that doesn't crash in these cases, but it will cause memory leaks with older versions of NWNX Core.
