Went through & followed the tips about logging out/in on the profile which did help some when playing Skyrim though here's the following issues still present. Initially I was about 2/3 of the way through the achievements in Skyrim on this profile, after the reset happened I had two. To get the achievement list partially back I got a 3rd achievement in Skyrim, though the list of games seems about right now after achievement #3 today in that game, the rest of the Skyrim achievements previously received are still gone. Also the total of all the gamerscore items is still pulling just from Skyrim & not the 100+ games I've played over all the years with that profile.
Also last night when I went back to playing Skyrim there was a 10mb patch that was downloaded, not sure if it matters but aside from that & the resent XBL update there hasn't been any roaming profiles or use of the cloud saves with this profile in the last few months.
