Issue:

If two custom skin packs are imported, expanding "The Traveling Trader" will redirect to "Rockin' Holiday Skins" and the rest wont be able to be expanded.

If more than two custom skin packs are imported, every skin packs will not expand no matter what I try.

If a custom geometry skin pack is imported, every skins in the pack will not be able to be equipped. You can select them but they won't appear in the preview, instead, the basic skins are shown.
