So for some reason my game stops and I can move but not interact with anything than I get kicked to hub and the following says "the server you were on is now down. You have been connected to the hub." but the factions server isn't down. Also this only happens for faction.
I would recommend, for any server that supports multiple versions, always use the lowest version, because it usually has less glitches and such.
I think its your internet issue. If your internet is too slow, the server will force you to go back to the lobby/hub
