Key word bug 26/12/17
Was in at magens and the scroll npc grave disappeared after a few seconds. The skele on top of it turned invisible and was still attacking me. The scroll skele reapawns a few seconds later
2nd time this has happened. Once here and once in Emmy cave

Game goes through and respawns a monster every minute or so, can cause that to happen sometimes if an npc happens to be standing on the grave(altho its really unlikely)
