Can't find event skin

Recently I have lost the steampunk skin that I had gotten from logging in every day during an event late last year.  I had just updated so waited a few days in case it was just a minor bug that would soon be fixed, however, it has been a week, and searching online and trying various fixes has not worked.  My character how was using all the pieces has turned into Steve, and I can't locate any of the pieces.  One character who I equipped with the jetpack back item still has that, although I can't locate the jetpack anywhere and have not tried to unequip it in case it is lost as well.  As this was a piecemeal set I got for logging into the market I don't have s skin pack to try and locate it that way, I just loaded each piece onto my character from all available.
