GTA4 updated this wekend.......played missions replayed????

[Oyeve]

I havent played GTA4 in a while and popped it in my 360 yesterday and was notified that an update was available so I did the update. I started playing the game and noticed that missions I have long passed and accomplished were available. I though, WTF?!?!? I did these missions long ago! Anyone else see this happen? I did all the McReary missions and now they have all reappeared as if I didnt play any of them. No big deal as they dont really affect the game much but its a PITA to have to do them all again.
