Advanced rubble and building crew

If a buildings spawns a crew after destruction, but it also uses the advanced rubble logic, then once the rubble building is created any crew will be trapped inside the building. Furthermore, as long as the crew stays there, engineers won't be able to fix the rubble, with the game kicking out any engineer trying to enter and EVA announcing "unable to deploy". You have to either somehow kill the crew or destroy the rubble building.

It should be noted in the manual not to use Rubble.Destroyed= on buildings with spawning crew.
