Random radiant encounters in the world are not cleaning up properly, ones such as Balbus, an old orc who wants a glorious death and the sabre cats around him some kind of mage and several others there is one location in one of my games that had around six corpses in one place I am pretty sure I started having this bug with 1.4 and I have created a new character with 1.5 and the bug is in this game as well.

I do now wait near the bodies I go to my house and and go inside of the building and wait a month or two months and I have even waited three months and they have yet to clean up.
