A little while after i had issue 645 i got this error when stepping on a corpse. Was unable to close the error box and continue with my character :(

A controlled JADE error occurred.
Please see the stack trace for details.

de.adom.jade.JadeError: Both map and carrier were undefined for giant rat corpse. This must not happen!
