Covers disappearing from my vault

Taiyed311

I had three Spiderman covers in waiting. Once I got him to 166 I was going to use them to infuse him into a champion. But now that I'm just 5 levels away I go to look and there is only one cover in my vault. Did something happen with the update?

It cannot be an issue of space in the vault. I have a lot of other covers in waiting that I have been holding on to. I noticed this earlier once. It seemed a Mohawk Storm card went missing but I though I just counted wrong at the time. This time I am SURE because I have been salivating at using the Spidey cards.

Earned covers expire two weeks after you've earned them. It says on the screen when it expires.
