Cities not growing bug due to unhappiness that doesn't exist - please help!

[Jimbojoneshello]

Hello everyone, I'm playing a emperor level game with Shaka and have noticed that literally all my cities have stopped growing, even though I have a food surplus in each one and my empire is not unhappy. I've hovered over the food icon on the city screen and noticed that for some reason my surplus has been reduced by 100% because of apparent unhappiness. I'm using the Communitas interface mod and that's about it. Screenshot attached below. Many thanks. (I should add that I have definitely not accidentally pressed the avoid growth button).

Note in the attachment that you can see that while my empire is in fact happy, for some reason I'm being penalised for unhappiness.

This may be a bug in the Communitas interface mod. This thread discusses a bug involving happiness and food surplus. It's not exactly the same as your situation, but it may be related. A possible fix is linked in post #18 of that thread. If that doesn't help, consider posting in the Communitas forum.
