[1.1.39] Bot blocked by cliff not marked for destruction

[gHoST INFERNO]

tl;dr - Bot gets blocked from placing entity due to a cliff that was not marked for destruction.

See attached picture. I placed a large blueprint, everything visible is covered with roboports, the robot tries to place that piece of rail but is blocked by the nearby cliff, but that cliff was not marked for destruction when placing the blueprint, so the robot waits forever. The blueprint was placed with shift-click to destruct any such blockages.

I actually also saw a similar issue, but presumably a different cause, but forgot to grab a screenshot before resolving it: A robot right on the edge of the roboport-construction-coverage tried to place a piece of rail, but was blocked by a tree that was marked for destruction /just/ outside the roboport-coverage -> robot waited indefinitely. This one could be argued to be intentional.
