Sorry for the delay on an answer, but the mod author is not automatically notified upon discussion creation. As far as the bots go, it could be that they do not have constructions they are capable of doing (minimum skill level not reached), they don't have the materials to do it, the job is not within the zone they are allowed it, or your load order is incorrect. There is an image in the preview for the mod that shows correct mod load order.

Thanks for the reply. I think it was the load order as you suggested. Many thanks.

Hi sorry to bring back this thread after a while, but I thought this mod only added cleaners and haulers. What mod brings builders?

Misc Robots ++
