[GAME BREAKING BUG] Using Planar Binding on Fiends in [SPOILER] area makes the spellcaster permanently hostile

[Memmo]

Game-breaking bug, but spoilers below.

Using Planar Binding on the halberd fiends with Orthon inside Shar's temple will render the spell caster permanently hostile towards other party members. This hostility persists through the fight; through deaths, through escaping to the camp (you fight them inside the camp). Breaks the game as it makes it impossible to do anything afterwards other than engage in combat.
