What gameplay feature is this bug affecting?
Hoard

What's the issue? Please include any error messages you receive and as much detail as possible.
So, I was feeding my lionesses with meat going to expire right in the "expiring" section and it started bugging out. My mouse has huge sensitivity so oftentimes it will double click and when it does, the invalid message pops up but goes away after I reopen the hoard. However, this time it marks it as "0 uses" but when I click it, the "Invalid item!" message pops up and when I go back, it is still there.

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

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:
1. Go to expiring
2. Feed a lion food and somehow click the food item twice even if it only has one use left
3. Leave to get rid of the message
4. Go back to the expiring page
