Title: Loot not showing what was received
I redeemed a chest and got a message saying I unlocked a skin permanent. It did not say which one, and did not have an image of the skin. I had to go to collection, and it turned out to be a chroma for Surprise Party Amumu.
Not sure if it's consistent or not, but I dont think I've ever received a chroma from loot before. Reproduction would just be redeeming a chest that gives you a chroma.
