What's the issue? Please include any error messages you receive and as much detail as possible.
New King that I kinged earlier today: https://www.lioden.com/lion.php?mid=61021
Old King: https://www.lioden.com/lion.php?id=794112291053

I'm not sure how much of this was supposed to happen and how much is actually an error. I looked around a bit and didn't see anything.

First of all, my current King had everything equipped to him get used again. This resulted in me losing a use of my lab test frog, and my Loving Leoponess that was equipped to him prior to being kinged is now gone because there's only one use on them.

Second. I don't think this is a bug because it's considered under the mutation/pose category, and I don't know if poses get carried over after you King a new male? But he had a Kind Pose equipped as well. And I'm not sure if that was wiped because of whatever happened with the items? Or if that just wasn't going to transfer over anyway.

Third. My old King was 15 today, and I know this because I was counting down the days to replace him xD I was so excited. And I just saw he magically gained a whole year after I replaced him? So he was 15 this morning, I replaced him with his son, and now he's 16. I know running a pride is stressful but damn, gaining a whole year in a day? (Lmao for real though I'm not sure if this is a bug or not.(

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
Nah, just replacing a king as soon as he turned 15 with his son.

Any screenshots you can provide us with?
No screenshots! I didn't think I'd need any because I've never had issues with retiring my kings before. (This is my secondary account.)

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:
Equipped my heir with a lab test frog, loving Leoponess, and the Kind Pose. Waited for current King to turn 15 and then had their take over for his dad!
