[1.15.2] World Loading stuck at 90% after removing the mod

Minecraft 1.15.2
Forge 31.1.47
Valhelsia 15.0.2a

No other mods than VS are used on generation
No mods are used when attempting to enter the world

I've generated a world with VS present, flew to a random structure and left the game. Then I removed VS and tried entering the same world. It gets stuck on 87% or 90% loading. The game doesn't crash compleltely but freezes without the possibility to do anything.

I've tried removing the spawner block and the code surrounding it previously with the same result so that doesn't seem to be the case.

If this is happening after the mod is removed, then I have to assume that the bug lies in either Minecraft or Forge (well, probably Minecraft, but Forge can patch Minecraft to fix vanilla bugs). It's almost certainly a bug that was triggered by Valhelsia Structures being there and then removed, but the bug itself isn't in the mod.

Specifically, the vanilla code appears to be missing a null check. I haven't looked at the code yet though, just the stack trace. It may be possible that we can investigate further and then forward something to the Forge team once we know more.
