How can I get my Season 2 gold skins back?

I was transferring over Siege and the add ons to my external hard drive from my Xbox One memory. Half way through transferring the game over my power went out. When power came back I transferred the game and other skins I bought over to the external hard drive, but the season 2 gold skins and regular gold skin (one that came with the game) have disappeared.

It doesn't show up in recently downloaded section, installed or even in the game. How can I get them back/ where would they be?
