I encountered a very peculiar bug in which while playing split screen local multiplayer neither my friend nor I were able to hit the confirm button to change our skins mid-game when viewing all the skins in a skin pack. As a result, only the first player can change their skin as it must be done from the title screen. What's odd though is that during split-screen multiplayer we are both still able to hit the confirm button when viewing the first six skins in each pack via the "Choose Skin" menu, and only when selecting the "+" icon to view the full skin pack the ability to hit the confirm button becomes grayed out and cannot be selected.
