Does anyone know what the crate icon beside the alicorn and dragon mean? I got really excited because I thought it meant I had them in my inventory, but I looked through all pages and couldn't find an alicorn. I do have a dragon egg in my inventory from the forbidden roost (I'm currently working on the goals to hatch it), however I also have a manticore, which I put into storage momentarily to see if a crate icon would appear, but nothing changed. So I'm just wondering what the crate icon means.
Sorry if this has already been discussed, I searched a little bit, but didn't see it mentioned anywhere... thanks for the help
