For a while now, there has been an issue where Xbox owners would occasionally "lose" their gamerscore
for a few days. Since it would always eventually return, it was more of an irritation than anything else but luckily for any achievement hunters — so pretty much all of us, keeping in mind what site we're all on — it's one irritation that Microsoft are set to soothe with a fix.
The good news was revealed on Twitter by Mike Ybarra, the Corporate Vice President of Gaming at Microsoft.
As Ybarra says above, the fix has been deployed, so hopefully, any missing gamerscore returns home soon, if it hasn't already.
