It says this when I try to load fabric 1.17.1:
Found conflicting mods: origins conflicts with {optifabric @ [<=1.11.18]}
Creating` Empty clause ?

Idk if I misunderstood the changelog in the latest origins file (1.17, 1.17.1: Origins 1.0.3) tho and origins + optifabric just dont work together but yea, this's all i know

The mods are currently still incompatible, but the OptiFabric dev will maybe update the compatibility again as they have done before.
