I’m getting a similar connection like this but i’m not sure what is wrong. Other’s can join just fine. I also was in just fine. However when I left and rejoined I can no longer join fully. I just see that sky

Reproduction Steps

  • Open Curseforge with the same modpack as the server.
  • Press play and go to the menu of the game.
  • Go To multiplayer and join server listed here. Then it loads and I can see my player but it looks like i’m in a sky with nothing around me. Commands do not work either.
