[Fixed 1.05][Bug 1.04]Crash when double removing resource importer

In this save file, look for the resource importer about halfway down, slightly to the right. There are two supply depots next to it and a big ugly “X” made of conveyor belts. Upon loading the level, go to that importer relatively quickly, then right click on it twice, once to delete the importer, and again to delete the resource conveyor left behind. Wait a few seconds. For me, this is a reproducible crash.

I was unable to reproduce on a smaller map.
