The standard Psionic Line of Fire mod works only for vanilla game [...]
Mods have to create their own versions.
This does not help here. I have a mod where all the psi weapons should be line of fire (well, unless my perl script did miss one), see below, but at least the oct still can attack without line of sight. But it is always nearby, may be some little hole at the edge of a room or elevator tile or something.
Or is it a problem with intelligence, if they have spotted the troopers once?
Well, when the AI starts cheating, I cheat back and hit my I-win-button...
