Got a couple of skull quests in last night (after having to wait 3 hours after reset to get into the game, but that's just standard nowadays) and then couldn't get any more quests to run.
Cleared cache - nope
Cleared data - nope
Again this morning - nope
Cleared cache again - nope
Clear data, uninstall, reboot, reinstall - nope
I can start the game and get in to select something, but just get the loading screen and stops when trying to run any matches.
Guess it's your way of telling me I should stop playing the game.
