Planar Prison Problem, Say that three times fast Options

[OldManPaco]

So there we are beating on the huntress waiting for her immunities to where off and that Tagget guy turns red on me about half way though the battle. He attacks and dies when Viconia sneezes on him. I miss his little dialogue but no big deal right?

I go on and clear out the area but when I get to Raelis she is also red. She says her dialogue about opening a portal but attacks me right afterwords. So I'm stuck in the prison with a bunch of dead actors. Good times.

I have done the whole level twice and the huntress battle three times with the same results. Every time Tagget turns red and attacks me while I'm waiting for the huntress's Immunity spell to wear off. This is after all the other minions are dead and I have someone beating on the huntress to keep her occupied while the rest of the group stands around scratching their asses. I am assuming Tagget is causing Raelis to also turn red.

So is this a 'feature' - is there a time limit to kill the huntress or am I just hosed?

Are you sure there isn't some spell or ability you're using that is causing Tagget to turn hostile? Seems like the most likely explanation.

He didn't turn hostile in my game, but I was very careful not to injure him or cast spells that would piss him off, since I know he's kind of important to completing that quest.

If you're not doing anything like that, it would certainly sound like a bug, though I'm not sure if it's IA related or not. What other mods do you have installed?
