I wonder which of the devs put the corpses into/under one of the house...
One of those dissease alts kinned me some good long time ago, and since a while I see his name in one of the buildings. ^^
Instead of "disposing" them in such a way, why not simply delete those corpses on a regular basis?
You could have an automated script that deletes all corpses placed in the cemetary area in town each sunday at a certain time, maybe after/during the sunday church mass, could be locally announced by an npc there...
This would ofc open up an option to completely dispose a body out of the game which is by legit means not possible iirc, but i would still say it's a good thing.
Whoever invests the work to get his ancestors corpse to town this way, should be allowed to assure him resting in peace.
