[sirpancreasjr]

In map view, I attempted to remove a rare construction robot from a roboport by right-clicking:

What I expect to happen: the robot is removed by one of the common robots.
What actually happens: the rare construction robot seemingly attempts to remove itself. It flies out, visits a storage chest, and returns. It accomplishes nothing.

This happens consistently until the robot is summoned for some other task, or the roboport runs out of space on the return flight.

Please let me know if you require more information. This is my first bug report and I'm happy to help!
