I was on prison island. Ran down the jetty and jumped in to the water, the character went underwater instead of swimming. walked back to shore to then swim out but the character just walked underwater again. I began to walk back to main land and I was kicked from the server. For the following hour I couldn't rejoin that server (Blue Waffle #2) but could join others, when I could get back on my character was back on the shore at prison island.
