Here's my latest log file.

I close the program and it looks like it quits, but Steam still shows it as running.
If I launch Resource Monitor I can see that the AnisopteraLauncher.exe is still running in the background.

If I end process on the launcher app, Steam then does the syncing thing and shows the game closed.


The problem only happens intermittently, so I haven't been able to nail down what the cause is.
I frequently Alt-tab to other programs while the games is open so I can get things done ... I'm assuming that might be a possible cause.
