Hello, I am the dev for Repurposed Structures. I had noticed an issue with a few biome mods in 1.18.2 that my mod's structures and datapack structures are not spawning in the modded biomes.

In 1.18.2, Mojang allowed any worldgen registry to have tags. Including biomes. They then improved the json system for creating worldgen structures which now uses biome tags for what biomes to spawn in. As a result, biome mods not using these tags will not spawn modded or json structures that uses biome tags.

I have more info here along with resources on what biome tags are available to use and add to.

Just ask me if you get stuck or need help. The biome tags would go under /data//worldgen/biome/ folder

In this case, I think you just need to add to minecraft:is_forest biome tag and you're golden!

Thank you for the suggestion! I'll look into this soon. I'm a bit new when working with biomes after 1.16+ biome rework, so thanks for the info. I'll add biome tags support in 2.0.3 for both Forge and Fabric then. ^^

Implemented in 2.0.3 for both Forge and Fabric. Enjoy. :)
