yeap, you seem to be onto something ... can only play quick ranked matchs, the worst of all modes btw ... smh ...
reset my router and nothing, still cant play any other mode online
, now it only says due to network problem ...
P.S (last minute edit):
Can confirm that it is not me the source of the problem but 2k, as I could play a teamup game with another user ... which isnt a fix but a workaround, nor even the ideal workaround as I lose everything and have to start from scratch ... and having 2k12 experience, would imply me doing this like 12 times or more.
2k12 servers were shut down ... as for you not experiencing the network issue, I didnt experienced with 2k13 until a few days back ... so sit tight and pray it doesnt hit you because if it does, you will feel overwhelm, powerless, abandon and full of rage.
