ClearFont2 is finally irreparably broken for me, whether or not I have AtlasLoot enabled. :( I feel so sad. I can no longer read half of my UI, even with Fontifier installed. Someone, PLAIZE HALP. Thanks! :)
For reasons I don't understand, I can get ClearFont2 to work but only if I have AtlasLoot enabled as well. I hope that info helps others to get the addon to work (though it's probably some weird fluke).
