Well i just found newscorebug.iff file on Online Data/downloads folder with other probably new files (252,954B replace by 294,213B)
it's happens to me when i wanted to play on-line game i got a message that said "there is new content need to download"
i just wonder if it's means that PC gamers don't need to wait until next new year before they will get the real 2k13 game and not the alpha
maybe the next update will include fix for 1 sec Replay...
and maybe someday we will get the AllStar content...
