[2.0.32] Crash changing circuit "SignalIDBase.cpp:320: Unknown enum value"

[<NO_NAME>]

I'm not sure what exactly caused the crash. I cannot reproduce it.
I moved a lot of elements of automatic train station around by Ctrl+X them. Then I decided to Ctrl+Z all that and after about 10 Ctrl+Zs the game crashed. The things I moved was combinators, power poles, train signals, walls and wall gates, some concrete tiles... idn. Most of it connected with green and red wires.
It is possible that I've actually pressed Ctrl+Z too many times by accident and undid something else entirely. All I know for sure is that Ctrl+Z was involved in the crash.

Well... apparently it's not Ctrl-Z. I've try to reorganize my station again and the game crashed even that I didn't press Ctrl+Z a single time. This time it crashed when I was removing a red wire but I'm not sure this was the cause.

Edit: I tried to load the save and do it again a few times but there's no more crashes.

Thanks for the report. Due to the nature of "can't reproduce, crashed in random ways" I suspect this is failing hardware. Unless you know of a way to reliably reproduce the crash from a known good save file?
