Right, On launch night i was at a friends with my account playing gears 3 offline (due to him having internet problems) i was using
my account and
my gears 3 save.
We ended up playing horde and beast mode and we got the achievements "welcome to horde mode" and "welcome to beast mode" and i was pretty certain i got the challenges and the skins for doing it.
Anyway when i got back home to my console the next day and fired up gears with the same account and same save my achievements were still there, But! the challenges for both those achievements were not done and i havent got the skins :/
iv tryed repalying them again (that dosent work) clearing my system cash ( that dosent work either D: ) and im running out of things to try.
Does anyone possilbly have a solution to my situation?
