Why did you remove those tree holes that chopped down trees left behind? It made it easy to automate a plant robot.

They never removed it as it was never a feature in the first place (I think, I played since ver 3 and have never seen a tree leave behind a hole). I would suggest that you automate tree farming by having a few bots doing these jobs.

-Digging holes

-Planting

-Chopping

-Logs/Seed collection
