Invalid Packet 1

[DapwnageG]

When i join a server. After a little bit of  loading it will go back to the menu and say "Invalid Packet 1"

Can someone please help with this. i really dont want to reinstall it because i dont want to lose my builds.

But that doesnt happen on dedicated servers for some reason.

re-install blockland or delete some recently DL add-ons =\

even if you re instal, keep the old folder, open it up, go to saves, and drag them to your new folders saves, then put them inside the correct place
