Uncooperative Myconian Hunters

[Jingo139]

While i was attempting the first mission of "The Glast Gambit" quest twice in a row i had a situation where the Hunters wouldn't open the last door, in the case of the first attempt only going to open it after i killed off the infested near the door using an AoE ability and the hunter on the other side died, and the second time i had 2 hunters who both stayed away from the door at the barricade even though there were no infested nearby.I don't know if this is common at all and i wasn't able to get screenshots unfortunately
