What gameplay feature is this bug affecting?
Breeding and Heat Requests

What's the issue? Please include any error messages you receive and as much detail as possible.
I recently traded a lioness and assumed that the pending heat request that she had would be cancelled when she was traded but for some reason it still exists in my incoming heat requests but I can't remove it. I am only given a message that says, "This is not your request to reject." I've had a similar issue before where the lioness did not exist anymore but I still had a request but I couldn't remove it because it gave the same message.
I sincerely wish that if a lioness is traded, sold, chased, killed, etc that the request would just automatically be removed, like what happens when you breed a lioness to your own king when you have sent a request to another king beforehand wherein it removes the request to the other king automatically.

Any screenshots you can provide us with?
None that would be useful.

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:
As far as I know it was simply that I owned the lioness, someone sent a request for her heat, but I traded her before I could process the request and therefore she was never bred by the heat request sender and I am unsure if the new owner can see this request or not (but I don't assume they can as heat requests aren't even on for her in their ownership).
