I have currently read the gamerscore correction FAQ and have noticed a few things it says people will get their gamerscore reset if they have abnormal gamerscore activity or getting achievements in an impossible order.
I have both of these but the achievements have glitched, on Borderlands my friend was killing Crawmarax to get me the level achievements, My level was increasing by around 7 each time so i didn't receive the level 5 or level 20 achievement until i logged on the next day, So in my gamerscore history it says i receive the achievement for level 10 and level 30 achievements before the level 5 or level 20 achievements.
In Doritos Crash Course i received a few achievements while the game said that i was not playing it, It was originally downloaded with another account, after changing hard drives i forgot to re-download the license so it said i was playing the trail, however i received an achievement, so in my game history it said i hadn't played the game for a few weeks however i just received an achievement.
In Halo: Reach i had bought a piece of armour and received the achievement for buying something that required Lt. Colonel, however i was not that rank, nor did i buy something that required the rank.
And Finally on Section 8: Prejudice i had downloaded the trail and fulfilled the requirements for a few achievement, i liked the game, bought it and received all of the achievement at the same time.
I do not want to reset because of glitches, and was wondering if the above would warrant a reset.
