Tested using 0.19.3 Loader of Legacy Fabric and Ornithe Gen 1 (it's what the installer generated using 0.15.0 Ornithe installer), using 1.13.2.
Mod Remapping API 1.27.3 or 1.29.0 (Legacy Fabric/Ornithe) and Fabricated Rift 1.3.0 (Legacy Fabric) and 1.3.1 (Ornithe 1.13.2) with OSL 0.16.3 and 0.18.0 (Gen 2 so not related in testing)
Tested using featurecreep-4.0AM18-1.13.2Rift.el9fc4.noarch.fpm.jar (latest build of FeatureCreep).
Crash report states Fabricated Rift errors with prelaunch errors, invocationtargetexception and other class errors, notfoundexception, illegalstateexception.

Tested using omnilook-0.2.1.jar, states requires version 1.0.0-beta.7.3, any version between 1.3.0 (inclusive) and 1.12.2. (inclusive) or version 1.14 or later of Minecraft but only the wrong version is present 1.13.2

Hadn't done testing with OptiFine, Modern Mixins and Tritium but they work now.
FeatureCreep is the newest 1.13.2 mod came across during testing.
I don't have hope in my testing and may have messed up builds disabled or active jar files in testing, so I'd say do as much thorough testing as can with what is available.
