After starting a new game I was going to promote a couple of people to farmers, I ran into a little problem.
After using the first hoe to promote one of my citizens to a farmer I went to the 2nd one to do the same, but in my haste I forgot to check the names…turns out I promoted the same person twice and she is now in a permanent promotion cycle.
Steps to reproduce:
Have 2 hoes
Promote the same person to a farmer twice.
Enjoy neverending promotion sound ;D
Edit: Might also apply to other jobs, havn’t tested yet.
