Hello! Just as the title says, with the latest beta on 1.20.1, steps to reproduce:

• Play with the mod,
• Teleport to the end, fly out of the main island, game freezes indefinitely
• (If on a server, the server stays open and no error appear)

Edit: Just noticed it has already been reported in the closed issues already, my bad!

I've just put out an update that fixes the issue. See if that helps.

It works, thank you ❤️
