AI issues (party members and charmed creatures)

I don't really know where to ask for help on this, I've tried googling it but I haven't encountered any mention of this issue.

Mods I have installed...

BGT
BG2 Fixpack
gminion I thought this might be the problem so I removed it, but no luck.
GUI mod
Widescreen mod
BG2 tweak pack

I'm doing a fairly a fairly mod-light run through of BGT, but I'm having strange problems with party member scripts.

Standard Attack (agen) doesn't work at all. Spellcaster Attack and Defend don't discriminate between friend and foe (or neutral) - with spellcaster attack the character will attack anyone that casts a spell, while spellcaster defend causes them to attack anyone that attacks a spellcaster. The spellcaster scripts and ranged scripts somewhat more consistant, they do engage enemies when they come in range, and only rarely start attacking an ally for no reason.

In addition charm and dominate spells don't work right - the creature doesn't change it's behavior, whether it's savaging my party members or whatnot. (charm animal on a neutral bear and it random walks around the screen ignoring my commands)

I forgot...

if I choose a script that causes a character to hide in shadows they constantly reactivate the ability - multiple times a second
