Encountered a crash when an autosave triggered as I was moving a section of my factory by cutting and pasting it somewhere else. After investigating it further I have determined consistent steps to reproduce this crash.

Select this roboport and the surrounding buildings (found near the Fulgora cargo pad) with the cut tool While the blueprint is held in the cursor, pause and attempt to save the game. On my machine this will result in a crash every time. Even if the blueprint is not held in your cursor the game will still crash on the next save as long as the blueprint is still in the copy history accessed with shift + scroll. If you cut this roboport and then repeatedly copy other buildings until the roboport blueprint is pushed out of the copy history then the game will no longer crash.
