Hi!
I'm playing beta 1.3.1 on a Mac.
I have 4 dresses in my character's outfit wardrobe, so 3 on the first page, 1 on the second page. If I click the top-left item on the second page, and then go back to the first page and click on an item on that page, a trashcan delete icon appears on the top-left "remove outfit" space. See below:
Similarly, if I click the top-right item on the first page, and then go to the second page and click on the item on that page, a trashcan icon appears in the top-right empty space on the second page. See below:
Same thing happens if I click the bottom-left item on the first page, a trashcan appears on the empty bottom-left space, and same again for the bottom-right and the bottom-right empty space.
On my previous save game, I clicked on the trashcan in the empty space, and an error appeared. I couldn't click anywhere so I quit the game. When I restarted the game, returned to the outfit wardrobe, and tried to change my outfit, another error appeared. I ended up starting the game again from scratch by uninstalling and reinstalling. Unfortunately I don't have screenshots of the errors, but from memory I think they were the same error as the above poster's error ("Failed to Load: img/.....").
I hope my explanation is okay!
