[Solved]

Like ideally I'd like if drones would only start working when they can deliver a full stack of items. If there isn't a full stack available, I don't want them constantly running around with only a couple of items.

But I'm not sure what should I change.

Solved - request_depo.lua line 195 change from "return 1" to "return stack_size".

Another issue: Request depos have a stack size of 200 so trucks suck up several thousands of stuff and deliver. Why is it so hard to understand what to edit to get what I want?
