Hey there @towerwizard ,
Thank you for reaching out to us!
This does sound like a result of your PC disconnecting from the internet while in Power Saving Mode.
Do you often have the game running when your PC goes to sleep / into Power Saving?
I wouldn't imagine this happening from a fresh start of your PC, as the connection won't have been interrupted in that scenario, but feel free to give it a try and let us know.
Thank you!
