What gameplay feature is this bug affecting?
Wardrobe

What's the issue? Please include any error messages you receive and as much detail as possible.
When clicking the import to wardrobe button on a lion's page, it doesn't load the whole wardrobe interface. No lion appears, only input for 8 markings show up and the items input is gone.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?

here is the lion I used for the screenshots, but it doesn't work for any of my lions, cub, adult, main male or whatever else.

Any screenshots you can provide us with?

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
Went onto a cub's page, clicked Import To Wardrobe. Try it pressing Import To Wardrobe on my main male and adult lions, same result.

The only thing that is different from this day than all the other days I've rolled over (Where it has worked) is that it's my birthday, could that be causing it?
