Not an issue (entirely) but i made a compatibility json for strata if you want to include it in the default config; however, strata has a few stone types with a special character "ā" that seems to not work in game for the variants. For now I've just replaced the letter with a regular a. I can provide the json if needed

strata.json
The formatting is a bit different than your other variant jsons because I had chatgpt do the gruntwork for me but it works in game. I've also left comments on the stones that use the "ā"

Also totally unrelated, but thank you for making this mod. I hope it eventually gets the attention it deserves

edit: I wrote this after looking at the download count on modrinth and thought it wasn't very well known. Regardless, thank you for this amazing mod

If you could either provide the JSON or open a pull request with it that would be great - I'll look into the special character and see if I can get it working
