Please explain your issue is in as much detail as possible.
I've had a few hard crashes to desktop recently and I can't seem to put my finger on any particular cause. Nothing notable changed with my mod setup or assets. It appears to be related to the game attempting to autosave, as the exception that gets repeated many times before closing is this:

728,015ms | Int16 out of bounds: 37652
at System.Environment.get_StackTrace()
at ColossalFramework.IO.DataSerializer.WriteInt16(Int32 value)
at BuildingManager+Data.Serialize(ColossalFramework.IO.DataSerializer s)
at ColossalFramework.IO.DataSerializer.Serialize(System.IO.Stream stream, Mode mode, UInt32 version, IDataContainer data)
at LoadingManager+<SaveSimulationData>c__IteratorC.MoveNext()
at AsyncTask.Execute()
at SimulationManager.SimulationStep()
at SimulationManager.SimulationThread() [Serialization - Internal]

This crash to desktop has happened three times now. Once after immediately loading my save game, once after a fairly lengthy play session, and once after a lengthy play session where I had put my computer to sleep overnight and then came back the next day. I did try disabling all my mods and wasn't able to replicate the issue, but then again I've only had the crash 3 times out of 15-18 play sessions with all the mods enabled. I also had to load a different save when disabling my mods, so it's possible it's something about my save file.

I tried running the Broken Node Detector mod and it didn't find anything amiss.

The complete log file is linked here: https://privatebin.net/?b836d6f357c97bd6#2WENp9QMafD8TsXuSC339NgoNLRARoGrKA9eFAiBPZDb

Saving the name normally seems fine, and most autosaves seem fine.

If anyone has seen something similar and has a suggestion I'd appreciate it.

Can you replicate the issue? If yes, please explain how you did it.
It's intermittent / inconsistent.

so it's possible it's something about my save file.

Please attach that here too, thanks.

Attached -- thank you!

The "Int16 out of bounds" error is harmless. How does the game crash? Does it give you an error or does it just shut down? Does the last autosave go through or is the saving process interrupted?

It just closes immediately to desktop — no error is given. The oob int seemed like the worst offender in the log; good to know it’s not the issue.

I will have to double check if the auto save completed if it happens again. So far it hasn’t repeated itself.
