When in the tutorial dungeon, I set fire to a poison cloud which in turn caused an explosion. The first problem I noticed was that the explosion did not stop, blocking off part of the level (I tried walking through...I died).
The other issue I spotted was that upon loading the quick save I made right before walking through the explosion, the explosion had reverted to the poison cloud.
