Robot seems to get stuck in a loop moving commodities between certain wagons, most notably with front pull/storage push/pull upgrades and compactor wagon in play. It will continue to move the same few pieces of wood/iron over even when the other commodity runs out. (Picking up/stacking items seems to be a pretty low priority action in general?)
On a related note, bot doesn't seem to pull from collector wagon at all... intentional?
If robot is going to use bucket on wagon/general/whatever it is command (5), can the bucket quest be adjusted like the rails quest (not counting as "picked up" unless switched to bot character)? Combining so many actions into one command seems to have made a few of the quests quite tricky to schieve with the bot.
