Recently I launched my new modpack, Ultimatum, with Iris Shaders, and inside the modpack is GeckoLib and Wonderous Wilds. After loading into a world, it said that geckolib is not compatible with Iris Shaders. Is this fixed, or an ongoing issue? I'm using GeckoLib version 3.1.26 for Fabric 1.19/1.19.2.

That's someone on the Iris team to look at they make changes to client ticking.

ah ok
