Happening here as well. Only on BE enabled servers.

I have tried multiple fixes:
Completely uninstalling AVG and Spybot
Eliminating EVERY non-essential system process
Updating any driver in any way shape or form related to networking

Nothing works except crossing my fingers that I can find the few servers that day that are unaffected for at least a few hours and of course all non BE Servers.

I'm having same issue. In addition it also resets my character looks to default black lady everytime I die.

I initially found a few servers that did not have the issue but now it seems like every server is rubber banding me all over the place. Was really looking forward to trying the alpha some more today (just bought it last night). Wish I could figure out which servers weren't doing it. It was easy to tell once you were logged as you could hit your jump key and nothing would happen.
