Good news and bad news. Good news is that MS has finally fixed their end of the timestamp issues. Bad news is that they screwed up not only achievements earned during that period, but some previous achievements from years ago. This means that timestamps will have to be rebuilt and re-scanned for every single achievement, across every account, site wide. This is going to take weeks and quite possibly, months.
With that being said, not everyone had an ongoing streak while this happened so there was no negative effect on them. So what I would like to do is compile a list of users in this thread who did have their streak broken by the future timestamp issue so that we can prioritize recalculating your timestamps first instead of having you wait another month for the site wide scan to hit you.
I will be going through some of the old threads where people initially reported being hit by the timestamp issue and be gathering some gamertags to start the list, but there's no question that I'll miss a few people. So if you don't see your tag on the list below please drop a comment and you'll be added.
Thank you everyone for your patience over the last couple of months and hopefully MS won't let this issue happen a third time.
Just a warning though, if you did not continue to earn daily achievements after having your streak affected then this scan will not fix it. Your timestamps will be fixed, but your streak will have still died either way. So please only comment to have your name added if your streak is still ONGOING.
