Skeletons disappear in Mistyvale
 

Multiple times now, I've been fighting Skellies in Mistyvale (the side of the wall where gob camps are, never had a problem on the other side) and they have just disappeared mid fight. No guard interference, no xp, they've done it at 80% hp and they've done it at 5% hp.

Wouldn't happen to be fighting them when it switches from night time to day time in game time?
