[0.15.37] Crash on error: "MultiplayerManager trying to create scenario but it exists already."

[PJB3005]

I was connecting to my server over LAN (so network error is unlikely) and while it was doing its thing (can't recall if it already finished downloading or not. Logs should have it I guess?), I resized the window to make it a bit larger. This took a while before the black screen was gone, and when it was I was greeted with a connection failed screen.

So then I just hit reconnect, and while it was loading, bam, crash.

Savefile: http://84.195.252.227/static/factorio_crash_save.zip (30 MB, NOTE: I doubt it's relevant, as this was the last autosave on the server when I tried to connect, not the actual file that got downloaded by the client. I couldn't find that anywhere.)
Log file's attached.

Potentially relevant, the logs on the server when my client crashed:

Thanks for the report. Unfortunately we have no known way to reproduce this problem and as such it's incredibly difficult to know if any change we make actually fixes it.

Do you know of any way to reproduce the crash?
