The stats page still appears to be messed up. I took a screenshot, but the page does not seem to want to upload it.
I am curious how achievements are tracked in the original Gears. I realize Gears 1 was made by Epic and not The Coalition, so decided to do some testing. I had been keeping track of my weapon kill progress, and should have been around 55 kills with both Frag Tags and Curb Stomps. I checked my stats tonight before starting, it showed 58 kills for each, so I should only need 42 kills more to unlock each of those.
First match, I got 23 kills with Frag Tags, plus 23 Curb Stomps for a total of 46 kills. That should have brought both kill counts to 81, and only needing 19 more. Second match of the night, I got 20 Curb Stomps and 0 Frag Tags. Upon completing the second match, Curb Appeal unlocked as it should have. After exiting the game, returning to Dashboard, and then shutting down the console, I checked the stats page. It had not updated my kill count, but did show I had unlocked Curb Appeal. I then turned off my computer. At this point, I am fairly certain that (at a minimum) kills on the stats page plus kills while logged in for a single session will add together to see if you meet the requirements for the Ranked achievements.
I waited over an hour, then started my computer, logged back into the stats page, and it still shows only 58 Curb Stomps and 58 Frag Tags on the counter. Tomorrow I will get 20 Frag Tags and see if I unlock Is It A Spider. If it unlocks as should be expected, then the kills are still counting even though the stats page appears to be broken. If not, then it may be that only kills from the current session are being added to the kills posted on the stats page to see if you meet the requirements. If the latter is the case, it may be impossible for folks to get Seriously until the stats page starts updating again.
I won’t know until I do more testing tomorrow evening.
