Was in the hundreds of thousands before. Oddball and others seem to be missing as well..... Anyone else having this issue or a solution?? i have tried everything reseting router retarting xbox clearing my cache and reinstalling the multiplayer disc but nothing works i only earn half of the normal credits i normally get my challenges keep reseting i have been told that im on the back up server if that is so how do i get back to the main one
