Hmmm... the first time I've seen a message like this.
See the linked picture, message 5 in the message box:
"46 elements of our units are affected by our inability to pay their upkeep".https://photos.app.goo.gl/YRVqQeqC1YaMzEGK7
I seem to have denarii in the piggy bank so I'm not sure what the issue is. Allies?
What should I be doing in response to this message?
