That's unfortunate. Thanks for letting me know! I never worked with Schematica. It seems to work with Litematica (.litematic), WorldEdit (.schem), MCEdit (.schematic) or with a structure block (.nbt). The .nbt file was created in version 1.15.1 and will not work with structure blocks before 1.13. I have a .nbt file for 1.12.2 and prior that I didn't include in the world download. Let me know if you want it!
