Steps to recreate:
- File->New
- Etc->Clear Quest Filepath and click "Yes" (bug still happens even if you skip this step)
- Etc->Options->Settings->Auto-save Interval: 1 Minute
- Wait 1 minute
- Observe Saving Quest msgbox briefly appears
- Observe "Untitled Quest" still appears in ZC Editor title bar
It appears to have not actually saved, because shouldn't the editor pick a filename?
