Player movement freezing mid-game and no error message shown. Happens about twice a day (mid dungeon of course).
Client seems responsive, can rotate, open Inventory etc, but it requires killing the game via task manager to get it working again.
The internet connection is fine (we have another machine on the same router that's never hung)
Both machines are Win7 with all latest updates, and we have no clue why just one machine is randomly stopping working (acting like it lost server connection).
