@traincutter From another post I made regarding a similar issue,
"Ticking entity is a strange error, caused by an entity in the world you're joining. It's most common on singleplayer, but I think it may be caused by bungeecord on multiplayer (meaning the server supports multiple mc versions). If this is the case, try joining with the latest version the server supports."
If it continues, please DM me the server IP so I can search into reproducing it
