[1.1.87] Crash re-connecting to server "MultiplayerManager trying to create scenario but it exists already."

[hyspeed]

1. After firing artillery at many nests using Artillery Bombardment Remote mod, the server couldn't keep up and my client showed the "Server Not Responding" modal with the progress bar. After a few attempts to pause / unpause, my client was disconnected. I chose Reconnect on the dialog.
2. After re-connecting, I was immediately disconnected with Server Not Responding. I re-connected again, which resulted in the crash and error.
3. I expected to re-connect to the server.
4. I have not re-tried to connect, as I wanted to capture the log and save files.
