Relevant Aether 2 issue: https://git.gildedgames.com/GildedGames/Aether-II/issues/796.

This really indicates an issue with how block states are saved in Aether-II, so hopefully they will fix it on their end.

According to the Aether-II tracker they have fixed this on their end and will hopefully release a build sometime in the future.

we do need an issue here as people don't know if this is an aether issue or BC issue so they will come here and people rarely check closed issues sadly

https://git.gildedgames.com/GildedGames/Aether-II/issues/796
Fixed with 4c3be093.

Has the fix been released in a build yet? The curseforge changelog doesn't mention it...
