Same exact problem for me. So Ill throw in my exact situation and see if it has any relevance. So Im hosting a server and this happens when someone outside of the local network joins. I can join the server normally on the same machine / connection. But when you try to connect from a different connection than the servers on you fall through the world. I have two networks I use and have tested it multiple times and have had my friends test as well.
