My desktop wallet stopped staking sometime yesterday. It was showing unlocked but not staking. This morning I restarted it and unlocked it for staking only, and after a few minutes, maybe 15, it still wasn't staking. I'm not in front of it now so can't troubleshoot, but I was wondering if it was just me having that problem. My computer does need to be replaced, so that may be my issue
