i installed the newest version of light overlay and downloaded architechury and its conflicting with optifine? log here: https://dpaste.org/hqj4

Have a feeling it won't be the last time

It surely isn't, and won't be :)

If you don't want to keep the fix on your side @shedaniel I can move it here, otherwise I've marked out the versions OptiFabric breaks so people are aware they've got to either update (or backdate).
