My server too. I have like 4 players and get constant rubberban lag, DC's, stuttering, all the time. It's getting very frusterating that i pay $25 for this crap. This needs to be fix right now.
Your recent update just destroyed the servers! I cannot get my server to update now and other players cannot connect after their client updates. The current client version is 0.49.65.11262 yet server stays at 0.49.109.11201. I have forced an update dozens of times. Nothing happens..........
