So, I unlocked this achievement recently using Horizon which has been classified as unobtainable on TrueAchievements. I unlocked it after it was deemed unobtainable. Many other people on TrueAchievements also did it. Rock band 3 confirmed it is unobtainable on their Twitter here: https://mobile.twitter.com/RockBand/status/546429367283638272
Here’s the link to the achievement I unlocked: http://www.trueachievements.com/a67392/well-connected-achievement.htm
Am I in big time trouble for this? Please tell me the way to best hide it from Microsoft and others and DRASTICALLY reduce my chances of getting banned/reset because I really don’t want to lose my account or gamerscore. How do I hide this error now?
