This has been going on for 5-6months now probably, we've lost over 180 dinos and boss kits because the server kicks everyone while saving if you are doing Master Controller. It doesn't happen every time, but often enough that we went from a one in 70 fail rate at Alpha Master controller(until 5-6months ago, fail was our fault) to a 22 in 43 failure rate, of which all of those 22 times was due to the server kicking us. This seems to happen on a fair amount of GenesisOne servers, some more than others.
@lilpandaEspecially GenesisOne643 has been horrible, although I've also had it happen on other servers. I assume you track player<->server connections/disconnects and certain in game activities so it should be easy to verify/see the problems/pattern.
