Trying to select a skin from a skin pack chooses a different skin

Turning on the game today revealed that my previously selected skin had been changed to another skin in the pack. When I tried to change back to the skin I used previously, it'd instead select a completely different skin in the pack.

It's frustrating, considering I bought the pack to use the skin I was using previously.

Affected skin packs (from duplicate reports):

• Gendry's Tavern
• Medieval Texture Pack
• Stonehill Castle
• Samurais
• Demons HD
• Animal Ghosts
• Anime Idols
• Mob Agents

Steps to Reproduce:

1. Own one of the skin packs from the list above
2. Go to Dressing Room > Edit Character > Classic Skins > Owned
3. Scroll down until you find the skin pack
4. Equip one of the skins from the skin pack
5. Exit the Classic Skins menu

Observed Results:
The skin changes to a different skin in the skin pack, and if you press the Edit Character button, the skin changes again.

Expected Results:
The skin you equipped should stay equipped.
