in the tutorial dungeon: the mine before the chest for which the key is in a vase nearby (also known as the mine in the tutorial dungeon which is supposed to be disarmed) does not explode no matter what i do.
If that's the one just 'above' the fire zone...
In my case, it didn't explode from having a vase tossed onto it (unlike the one in the first large room, which blew up immediately), but hitting it from a distance with a spell did set it off. Something not quite right about its scripting?
