Same thing happens to me except my progress was rolled back today. I had the disconnecting issues yesterday but eventually was able to play. Logged in today and everything was fine until I logged off for about 2 hours and when I logged back in everything that I had accomplished since yesterday was erased. I ha completely leveled my both of my primary and sub classes, bought a legendary from the vendor, leveled up my gear, completed a few strikes for my exotic bounty, and the worst is that I farmed 100 spinmetal and all of it's just gone. Please fix this because I'm already getting tired of the grind for the smallest of progress and now I don't feel like playing at all.
