I've experienced two app crashes after closing laptop lid and moving locations.
I noticed the settings for Theme (all break) and General > Show Time Out Stats in the menu bar are not persisted after app crash. I reset them and Cmd-Q quit the app as well and they were not persisted either.
Re: bug: Not saving prefs after crash or exit
I'm sorry about the crashes. Did you provide information about them in the crash reporter window? That might help me trace the cause.
The supporter rewards are reset when you launch the app if you aren't a supporter. They will persist if you are.
