You can get this trophy by downloading your creations with a 2nd account, i just did it a couple days ago. Go on ur 2nd account and download your creation and then back out to main menu and go back in re download and overwrite save file each time. After downloading 5 times log back in on ur main account and go into comm creations and the trophy should pop. Worked for me a couple days ago. Times downloaded with say 0 but you'll still get the trophy.
