I have done a small test, and because i play with a stacking mod that changes stack sizes to 5k, i have found that if i limit the stack size to just 100, all operations goes VERY smoothly.
Will this request all the qualities in the network above normal? I would love a mod for this. Im swamped with quality items and i would like to ship them to the upcycler station
If you tell it to request that specific quality, then yes, it should give it to you, does for me.
