Currently on 3.3 if I host and someone joins me they can't seem to move beyond the starting point of the game. They load up but can't move and at times can't see anything. They are stuck in the beginning spawn point of the game but can't do anything else other than to close the game out. 

Tried multiple saves and other ways to get around this but isn't possible. I can join others but others can't join me. 

Hey Razeil! I'm sorry you and your friends have been dealing with this multiplayer bug. The team is aware of this bug, and it should be resolved when the content update drops. Please let me know if you're still having this issue after you've updated the game when it becomes available. 

Thanks for being an awesome member of the Grounded community!
