they generate with loot but do not get effected by lootr

I also have the same thing happening, is there a way I could fix this on my end via datapack or config?

Mine don't either, but how would that even work?
They're double chests and different, I think you'd need new art with like a 'lootr coffin'? Something like a double chest?

The actual chests in Graveyard stopped working at some point too though, and I'd love to see those be fixed.

Which version of Minecraft and which launcher? That's something I can look into; do you know which specific structures are problematic? It looks like they're all encoded as part of the structure NBT.

Sorry to the two commenters above for the hijack.

For the actual chests in Graveyard though:
We're using 1.20.1 with Prism Launcher / Forge 47.2.6
Graveyard is: "The_Graveyard_3.0_(FORGE)_for_1.20.1"
Lootr is: "lootr-1.20-0.7.30.73"

I don't know how to get you structure names/etc, but it seems to affect the actual buildings, Mausoleums/etc. I assume it affects everything in Graveyard, i've never seen a working lootr chest in a graveyard structure. What's the best way to get you the info you need?
