Mana said he's only got a couple grids left to go before he gets the skins, so he could be an alternate if Rolento and smog keep having problems. I would like to see everyone in the original group get the trophy, though. It's no trouble to wait.
smog, I'd back up at least your game saves at this point. I don't think you can back up the games themselves, but you could always do the deauthorization Stranded mentioned and redownload everything.
