Frozen on Trial of Sekhemas - no graphics update, but monsters still hitting me.

Bug report ref # 965,122,055
I was in the 7th room of the Trial of Sekhemas. I had just started it and hadn't moved.

Turns out I couldn't move, and no graphics were updating, but I could hear the game continuing, and the monsters were hitting me, until I died.

This has happened twice in Maps also.
