ok ,so if you wish to still retain it, add tags like INCOMPATIBLE WITH MANY MODS, IMPPOSIBLE TO INSTALL, DO NOT USE WHEN...
Unfortunately, BP is indeed very buggy in latest version. Until either Horred or a fixing-savvy person gets to fixing it, it should be marked as "expert" in BWS.
There's little reason for people to use it in current state, regardless of game - it's bugged on EEs, BGT, BWs, BG2, whatever. Enemies without weapons, mages casting spells on non-hostile PCs etc. are really not to reccomend to anyone. Who wants to play a game where Firebeard attacks you with spells when you enter the first inn in the game? And this repeats with a multitude of other (seemingly friendly) mages as well.
I do like BP (it does a lot of things SCS doesn't) but as it stands - it's unplayable without seriously hacking into it.
Fwiw, for people who want a smarter AI without SCS usage I'd highly reccomend Questpack AI improvements. Low key changes, yet decently challenging, and the whole install takes about 2 minutes, regardless of mods installed beforehand.
