I just want to play on my friend's server with them. I'm not sure if i had optifine activated as its a different minecraft launcher for the game and i dont know a lot about computers and mods. Some things included delteing my player data so I would have to start over, redownloading all my apps/mods, firewall settings and even resetting the server, to no avail. However if youre currently beneath the map, youll need to immediately type /home or /spawn as soon as you log in. I contacted the host of the server and they tried troubleshooting many things but nothing has worked. This morning i decide to try and actually play and anytime I loaded in I would only fall through the map for a long time and then disconnect. Eventually I got out and decided to log out, so I entered another house (with a normal door) and logged off. The door only half opened but I has ran into the house so I got stuck for a while. When I spawned in I tried to go into the nearest house.
