.. either that, or I'm doing something wrong, which is also very possible obviously. Worked fine before on 3.0.19.

Small demo of the issue:

(eh, sorry for the music, didn't consider that OBS would record that as well)

Also tried with chargeable items from EnderIO, Thermal Expansion and Mekanism – same issue.

Is this broken or am I being an idiot? :)

Cheers

Nevermind. I let the fact that it's configurable from any device trick me into not bothering to make a controller.
