Took a lot of digging to find out what is causing this... Once I did I verified that this is indeed a bug caused by BGT by testing it on a clean install
The AI script files agen and apass do not work, and when you load a game it will automatically change any character who is currently set to either of those scripts to have the ai script "none" (none is an actual script file, just an empty one).
All the other scripts have been tested and do not exhibit this behavior (the resetting to none, I only arang for actual functionality... and it works fine).
In the attached file you can see the two affected script files before and after installing BGT.
Reverting BGT to the before script file fixes this issue.
My install order:
1. GOG BG1
2. GOG BG2
3. BG2 Fixpack (all installed, beta included)
tested at this point and verified that it works and that the scripts have NOT been modified.
4. BGT 1.18
examining it at this point shows the scripts have been modified to corrupt version.
