[1.1][Crash] During tactical battle zip and debug included

This crash occured during the last battle in the Sauron(sp)'s egg quest.  I attacked the last opponent with my water elemental.  It started the attack animation then the battle ground graphics changed slightly.  Like maybe the shadows dissappeared, but I don't really know.  I can't really explain it except that it looked different for about a second before it CTD.  The attack never occured.
