nods I think part of it was that the construction manager was as much not sending bots out to do placing of solar panels due to lack of materials as it was sending out for ores
I'm not sure if there's a good or easy solution for coding (I'm managing my choices of when and what to mine a lot better for now as well as the other mod I made to keep 1000 construction bots free at all time which really helps)
Maybe, a hack though I'm not sure how good or easy, would be to keep the length of the construction queue less than 2x the number of bots in the system
