I first noticed issues after completing some of the newest achievements from the title update. I earned the achievements and still have the points, but at first it showed up as having the achievement 5/5, but then showed 0/5 etc. and it actually started recounting the wins on the maps. Not a big deal I thought. Everything else was fine though, until yesterday (2/21/09). I tried playing yesterday, and to my horror, all of my achievements and everything have been set back to zero. The game is acting like I've never played before. When I picked up a weapon for the first time it told me how to use it and started counting up my death by variety achievement that I completed a long time ago.
I still have the achievement points on my profile, but every collectible and kill from seriously 2.0 has been reset to zero, along with every other achievement counter. I was just about to break 4,000 kills on the 2.0 and had over 250 rounds on party like its 1999. I don't have a single stat that wasn't set back to zero, and now it shows I need to re-earn all the achievements. Even my online ranking was erased and now don't have a single stripe. I've also noticed a large gap in my online stats when i view them on the Gears page. Definitely missed several rounds from my january matches to the most recent late february match that showed up on the stats page.
Plus my game save is screwed up. I was playing co-op with a buddy on my game save, and we were on insane in "Aftermath" at "Free Parking" but when i try to enter that save with a buddy it won't let me. It starts us at Tip of the Spear and I can't select anything further. If I use that save in solo campaign, it starts me back where we left off the last time we played. I've never even started a solo campaign on Gears of War 2. We were so close to completing the game on insane, and now all my collectibles are gone and the only ones I needed to still get were the very last 2 in the final chapter.
Needless to say, I'm pretty pissed right now, all that work is gone. I just wanted to know if the people at EPIC know what the hell happened, and if it is reversible. I have no error messages, nothing to explain this oddity. I feel like the issue might stem from the title update that added the new achievements.
