Apparently this crash kept happening upon Maid trying to join.

Akane has reproduced the crash. It happens when getting close to Sahfy's base aka Suzy's mine.

@Empour had pushed a slab into her fairy light with a piston. Maybe that moved the block entity, and Fairy Lights does not expect that? Resolved for now by temporarily removing the mod, then adding it back. If nobody tries something similar again, we should be safe.

Reported at pau101/Fairy-Lights#74.

The issue was resolved by the mod, but I think we updated mods just a couple hours before Fairy Lights released a new version, so it's not currently in the latest pack version. Will close when we do another update!
