v1.03a. In my current game, I just rerouted the tail end of my line, diverting around Fit Electronics (now deleted), Quality Control, and Export, routing to a pair of Quality Control/Exports (no Fit Electronics!) at the top of my map. Loading this save on my computer, the game crashes about 7 seconds in; no action necessary. The game freezes up, although the music continues. If I click uselessly, eventually Windows pops up the "ProductionLine.exe has stopped responding.)
At one point I tried saving around the same time the crash might have happened; the saving screen opened, the gear progress bar moved a bit, then it froze. The save game looks suspiciously small; I haven’t tried loading it. If it would be useful, let me know and I’ll send it along.
(Also, is there a better way to get saves to your, assuming they’re useful for debugging?)
