I've not started having these problems until recently, but my connection keeps cutting in game, but when I come to test my connection it says it's fine. I literally have had to redo the same dungeon about 5 times now.
I have the same problem. The game is showing connectiion disturbances causing my game play to freeze but not totally disconnected causing me to loss battles. I ran a systen check 3 times, my connections and all is good, cleaned out the cookies and junk even rebooted the PC. None of what I did fixed the problem.
