[1.0.0] Hang when autosave during map annotation

[jypma]

I was having a longer session annotating map locations, when autosave kicked in during me entering the name of a new location. The game froze showing the "Autosaving" bar at 0%. I had to kill the process. The autosave file that was being created (ending in .tmp) was empty, so couldn't be read back.

Unfortunately, this happened more than 2 runs ago, so I don't have the log file anymore. I'll update this topic if it happens again.

Running on Arch Linux.
