I was adding more random objects to the "F" character from MrCrayfish's Furniture Mod, and I can't get variants to show up. For example, if I use cfm:modern_couch@3, I only ever get cfm:modern_couch@0.

I'm using lostcities-1.12-2.0.22 and Forge 14.23.5.2854.

(I don't know if it's related, but I also can't get Decocraft objects to show up at all. This might be how those objects are created, though)

Edit: Bibliocraft objects do show up, so this may be a CFM issue.
