Can't "mine" an lost construction robot over an ore field

[JasonCurnow]

I had a robot network that I was tearing down. After I removed the last roboport, there were a number of construction robots that were just floating around. Normally when this happens you can just "mine" them to pick them up. In this particular case, the 'bots were floating above a copper ore field. There wasn't any way for me to "mine" the bots to recover them - All of my right-click efforts just mined the copper ore underneath. I eventually got them back (by using the Watertiles mod and replacing the copper ore under them with water) but there should be some way "mine" bots back when they sit over an ore patch. Not a huge problem, but an annoyance.

Just reestablish roboport coverage, collect the bots from the port. Problem solved.
