[Outdated][Bug 1.07] Crash

Not a lot to report, Windows Explorer informed me productionline.exe stopped responding and closed it.

I had just cleared house to redesign my line. Everything built, was was going through upgrading all the stations with all upgrades. (for which I have a suggestion in the Suggestions forum)

I got to accessories when the crash occurred -I think it was Fit Seats but I am not 100% sure.
