Bug Report

Game crashes when I try to join any existing world. Creating a new one always works, entering an existing one never works. I tried checking every world with NBTExplorer and I tried reading the logs but I can't determine the issue, even tho it's always the same one for every world I try to join. I'm not running a test build from actions, but it doesn't let me create an issue without checking it.
