Hope this helps!

Running version 0.2.2 on Windows 7, Orc fighter (trying to survive longer than 5 minutes here), finally found an altar -- hooray! It was gray (uh oh). Dropped a giant rat corpse on it to see what would happen. Got the following error message, after which game continued to be playable (I clicked "continue"), but the item vanished.

----begin copy----
A controlled JADE error occurred.
