Every 5-20 minutes players get kicked from any server in conflict mode. The more players on the server, the more frequent the disconnects seem to happen. I have played on official servers and privately owned servers with both vanilla and modded conflict game modes, the issue persists on all of them. Some of the private servers are sometimes slightly more stable, but I have yet to make it through an entire match without a disconnect. This seems to be less prominent in game master mode, the few game master matches I have played had very few forced disconnects.
