Has anybody else had their progress lost or reverted back to a certain point on extinction? After I downloaded the onslaught map pack my xbox one was attempting to sync data and it took forever! After it finally started working I went to Extinction Mode and all of my stats and ranking from my previous match was reverted back to where it was before I started that specific match. Does anybody have any tips and getting it back? Did it have something to do with the syncing? Any help would be greatful! Thank you in advance!
