Mod name: World border
Mod version: 2.3

Description

background info: using cubic chunks and terrarium. Trying to make the world loop so you can easily move around earth.

shortly after setting up the coords in the config i launch the game and it i'm stuck in the air at about y=255. im at the ++ border(far southeast) and i cant see anything. i cant move or use commands. there's no way to leave the position or do anything about it. the game doesnt crash and seems to be stable (60+ fps). hopefully someone knows how to help me out.
Thanks!

Crash report
