When I play this mod in 1.12.2 (Version 1.12.2-1.8.0), the dungeons are completly empty and only made with stonebrick. I couldn't find any chest in the entire dungeon.

Screenshots:

It's a game-breaking glitch which already destroyed the generated chunks in my world.

Did you customize the dungeon configs? This is caused when the config files have errors, like a trailing comma.

I noticed this happens in Dungeons that create close to world spawn, and in modded Biomes (I see the empty dungeons consistently on the Landfill Biome from Dumpster Diving and other Biome O Plenty, consistently in the Marsh biome for example.

I was able to fix this in my own fork of Roguelike Dungeons:
