Resolved [NOT solved][1.5.4] Notification disappearing every day

[Noxxys]

After taking a city with an army that I'm leading, I noticed that the "Vote for the new owner of Myzea" notification disappeared right after appearing. I didn't have time to click on it, and the vote didn't take place, the leader of the kingdom stays the owner of the city.
Restarting the game didn't help. The same notification appears again each day, but as before, it disappears before I can click on it.
One time, the notification appeared right at the time I entered the menu of a village, which paused the time, so the Myzea notification stayed on. When I clicked on it, I said something about the event not being applicable anymore (I forgot the exact message), and I couldn't vote for the city ownership anyway.
After capturing a castle, I got the expected "Vote for the new owner" notification for this castle and voting worked fine, but the notification about Myzea is still bugged and appears/disappears every day, which is getting annoying.

Steps taken:
- Restart the game
- Disable and re-enable notifications from the campaign menu
- Take a(nother) castle

The problem fixed itself after a while. The Myzea notification appeared and stayed this time, and the vote took place. No more issues after that.

The problem is not solved. It happened again after taking another city (Onira). So I think it only happens with cities and not castles.

Here's my save file: https://1drv.ms/u/s!AvuEe73Ac2qw-2UBHpCBSPBYKKHv?e=x3cuMi
To reproduce the bug, just wait for 1 in-game day and the notification about the vote for the ownership of Onira will appear and instantly disappear.

If I manage to click on the notification (because I paused the game in the short time it appeared), the message displayed is : This kingdom decision is not relevant anymore.
But that's wrong, because the vote for Onira has not taken place yet, and it will eventually take place at some point, later.

Can confirm this happens to me, too. Latest beta. Notifications of elections flicker; obnoxious at most, the decisions still go on after some time.

Yes, for Onira the problem fixed itself after a few days. For Myzea it took longer. It looks random.
