What gameplay feature is this bug affecting?
Stat Gains/Item Usage

What's the issue? Please include any error messages you receive and as much detail as possible.
I want to preface this saying I know Dry Palm Leaves have the chance to give 0 stats. This is not about that. This is about when the usage notification says you've received stats.

Using the Dry Palm Leaf amusement item on a lion does not give them stats, even if it says it does. This definitely applies to the Smarts stat, I'm not sure about Agility.

(I tested it three times and never rolled any Agility stats, and I don't feel like wasting more leaves lol)

EDIT: This also applies to the Agility stat. I don't have a screenshot (did it too fast so timestamps are the same) but the 4th link "received" +1 Smarts and +1 Agility, but the stats were not actually added.

EDIT 2: From Falkenstern25 (#224312) - This bug is also present with Kudu Horns.

EDIT 3: From ~ BabyBunny ~ (#120065) - This bug only happens when using the item from your hoard. Using the item from the lion's page works as intended.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
Unsure if this only applies to certain lions, but I've been giving leaves to the first link for a while and I thought I was just trippin ;--; The other two I tried today and had the same issue. The third link is the one in the screenshots below.

Warning: These images are super long. Times are in EST (3 hours ahead of Lioden).

8:02am: I check Viola's stats. She has 30 smarts, 10 agility, and 140 total stats.

8:04am: I refresh Viola's page. She still has 30 Smarts and 140 total stats. This lack of stat gain remains even after refreshing 10+ minutes later.

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. Choose a lion and open their page. Mentally note their stats.
2. In a new tab, open your hoard and use a Dry Palm Leaf on that lion.
3. Repeat Steps 1 + 2 until you get a stat gain from the Dry Palm Leaf.
4. Refresh the lion's page OR open a new tab and go to the lion's page. The lion will not have gained any stats.
