Same happend over there. But I don't think there is something inloved with hack tools.

Since the way it happend to me:

I've been running near "Солнечный" and suddenly my character freezed and after 5 seconds I was teleported in the middle of ocean without anything around me.

There wasn't anybody near me, also I had friends in the server and they had no problems. It looks like random bug.
