What gameplay feature is this bug affecting?
Playing with Lionesses

What's the issue? Please include any error messages you receive and as much detail as possible.
When clicking the play dropdown button, the webpage crashes producing a STATUS_BREAKPOINT error code. This prevents me from choosing alternate mood-boosting such as grooming and tussling, as well as when one single-use play is used up and amusement items are necessary, I can not use the dropdown list to choose what item I want to be used in particular (such as a rib bone or a box, I have to use the auto-selected amusement item. There is a workaround to this by going to the hoard and using the specific item, but it does create extra unnecessary steps and a mild inconvenience.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
All lionesses in my pride are affected, but my alternate account's lionesses do not crash the webpage when clicking the dropdown.

Any screenshots you can provide us with?
