Locked inside room in vaal temple

Hello,

Quite the issue here, Cleared all the mobs in a barracks room inside the temple except one: a big scorpion in the middle of the room, doesn't move, doesn't attack, and i can't target it. Tried area damage or anything else, nothing. tried reconnecting, solved nothing. meanwhile the room is locked and so is the rest of the temple. Also checked every corner of the room for buried critters, still nothing.
