When using the latest verion of Aether and REI, the REI menu that shows all the items doesn't load. The mod still apears as loaded and no i havent disabled it with crtl + o or some other binding.

This appears to be resolved. Would recommend a re-test here.

The best solution that I have found is by going to roughly enough items and hitting the reload plugins button in mod menu (This is only a stop gap for anyone using the mod).
