The custom AI scripts don't work for some NPCs,
for example, I set Sandrah's custom script to customize -> script -> advanced AI (the default BGEE option), after clicking "done", the AI script obviously doesn't work, because Sandrah doesn't turn undead when idle, which has been set in the script. In addition, the AI script reads "custom (None)" in the character sheets.
Sometimes for some NPCs, clicking "done" doesn't do anything. the page stays the same.
This happens to Dynaheir too, but not the main character.
Any ideas why?
Saved game attached. Thank you!
