Every time I try to join the server it looks like it loads me into the world for a split second then I get "[Proxy] Lost connection to server" I was on this afternoon just fine. I wasn't doing anything out of the ordinary, just using my bound pickaxe to break some blocks around my base. No crash reports were generated either.
this is common for Hypo, theres something within the modpack itself breaking player data, had it happen to me twice in a row
