Hello BlackDiamond,
Thank you for your report. The behaviour is quite unusual, so I would like to investigate more. For example, usually after a power cut or network reset, my Shakes continue to try connecting to the servers until they find them again.
Could you please post the logs from the Shake after the event that you have described has happened? Without them, it is impossible to understand what is going on. Thank you.
Instructions on how to do it are here, if they are needed: Please read before posting!
