So I started up my aternos server, ready to play with my friends. When they join, however, it just makes them float in the void and they can't actually play.
On top of that, they also got a message after a couple of minutes saying something like this:
Help would be appreciated, the server is on fabric 1.18.2 (0.14.6) and the version of fabric they have is the same as the servers as well as the mods they have, so that is most likely not the problem.
