In addition to Bugsplat Crash Report #131099094
After this problem occurred I was able to connect back to the game, but unable to chat, move, or buy items. I did try to finish my Banner of Command, and on my screen it registered, but when I reconnected I was back at my old items. My ping was around 450-500 connecting to the game, and in game. When we finally surrendered, for the second it takes to register I was able to move around.
I hope something from this helps.
