No, never seen any of those. And its always completely random when it happens, sometime loading, sometime looking at map, sometimes just in battle, etc. etc. also window 8.1
Yeah the game runs horribly, and it gets worse each patch since PU2. When I started it was 2-3 hours between crashes and gotten only worse from there, with this recent one its gotten to be 20 min till crash. I pretty much wont play like that. Now as far as suggesting its our computers and not on there side, why does performance get worse, around the same time as patches, but computer specs dont? This coupled with the bugs make it at this time one of the worst running MMO's I have had the pleasure to experience. So yeah OP its them not you.
