Completed The Game = Can't Save?

[PPG xBuTTerCupx]

OK, so i was going to finish the game and find all of the items in every level first then go back for my jackanism chests...now the FAQ says if you get three heads you can save and then go to any level, but now that i have completed the game i dont even get the option to save? how am i supposed to go back to levels like tortuga to get my chests...(i have a few btw, just missing the ones on Tortuga/Davy Jone's Locker/Shipwreck City/The Kraken)

Edit- Do i have to go through the entire game again because i can't get these chests? i really dont want to but i want my 1000/1000

Did you watch the credits? I think it ask if you want to save after the credits are over.

You still have to go through the gsme twice for the jackanism chests and i saved after the credits like CovertDog said. :)
