I read somewhere that all corpses are supposed to stay for 2 minutes and then disappear but for some reason this is not true in the Broken forest. I have have encounters with groups of the slow moving undead and the combat lasts about 5 rounds and many of the corpses disappear before the combat is over. I have found myself looting the corpses while the other guys are still attacking to keep from missing the loot. Is there a special code set there or is there some other reason? I can't remember seeing this behavior anywhere else.
