Hello,
I'm trying to set up wireless charging using Flux Networks, but my main inventory charging says it's disabled, and I'm not sure how to turn it on (or if it's disabled for reason)

Because this wireless charging will always be on as long as you create your network and turn it on, but it's not like a machine, it's going to check all items energy capability/interface every tick (actually 4 ticks now), so it causes lots of lag.

Generally, players will charge their tools in hotbar, armor or baubles, so I disabled the main inventory from charging. As for why the inventory icon is still shown in GUI, that looks better >w<
