I've been having trouble with battlefield 4 since the feburary update to Xbox one.
I'm a rank 30 with plenty of weapon unlocks, yet when I start a multiplayer game in one of battlefields built in maps, my weapons become locked again. And when I go into the battle log, my progression jumps to zero. But when I go to the main menu under 'my soldier', all of my progression is still there.
When I play a China Rising map, everything is normal; my weapons and progression are untouched. But playing a built in map, everything is reset.
