Watchers Keep , bug?

[Avaran Exodous]

I just recently installed TOB and am still playing SOA. I am currently messing around in Watchers Keep on level 1 and keep hitting a snag or possibly a bug. Whenever I go into the room with the 4 slimes and one mephit no matter what I do somehow Jaheria dies. I can't ress her for anything and have tried several times . I cast the spell and she dies right away once again. This also happens by placing the bell in the alter by itself making the 2 statues come to life. Once there killed she dies as well. The one statue looks very much like jaheria equipment and all. I'm not sure if it's a bug or what.
