It would seem that putting the Void upgrade and enabling some items in it doesn't work. Pickup + Void upgrade works when the backpack is on my back (tested with Ended Pearls) but setting it up on the wall without changing anything in the upgrades with a hopper on top doesn't void the Ender Pearls

Mod v 10.4.8, Fabric 1.21.4

Yes, I know about this issue, haven't implemented proper storage interaction for fabric yet, because its' api is more complicated than neoforge. I will try to come up with something soon.

Alright, I see ! Thanks for the amazing mod tho !
