When I started L5 this morning, it requested a Crash Report which I dutifully sent. Further reflection caused me to realize that list night's exit was without incident. Cleared the logging folder and tried executing a normal quit and restart. Each one convinced Logos that it had crashed—The last one even convinced the OS.
