I may not have understood the question but I still tryto reload a steambot you (or any bot) must have a log in hands and the "given (or use)" it to the steambot
But how do i refuel it after it runs out? when its power supply is empty i cant interact with it to put more logs in it.
it looks like a bug...
but have you try to make this?
-when you have a log in the hands right click to give
-or go in the window on the right for access to the robot, trade and put the log in the inventory
When the steambot is empty, you can just right click it with wood (logs would be the best as they burn the longest)
