Also linking Minecraft boom issue here just in case:

MinecraftBoomMod/Minecraft-Boom#6

Issue is caused by a method in Minecraft Boom that sets a custom loading screen which conflicts with TheBetweenLands also setting it's own loading screen.

Disabling this in the config resolves the issue.

Fixed with latest Minecraftboom update.
