I've spent some adapting and adding to some of the default scripts to customise them to work better with my playing style, and I've encountered a problem which is really bugging me.
Jaheira's script is based on the Spellcaster Attack script (fighter3), with spellcasting I've added in, and a small component at the end to check the range to the party leader and move towards them if too far away (useful for when she runs off chasing enemies). My problem is this... While there's still enemies around, Jaheira gets all caught up in the fray and ends up battering Aerie. I can't see anywhere in fighter3 where this should happen. It only seems to be Jaheira and Aerie who are affected, and it's only with weapons that Jaheira lashes out. None of my other party members hate one another so much. Any clues as to where I should look?

Maybe you could show us the script.

Doh!

// * For Jaheira and other Fighter / Druids
// * Heal the party, heal yourself
// * Attack enemies with spells
// * Attack enemy spellcasters with ranged weapons
// * Attack enemy spellcasters with melee weapons
// * Attack other enemies
// * Return to the party leader if idle
// * Based on (and borrowing heavily from) Brent Knowles' scripts - fighter3.baf, cleric3.baf
