Neat, thanks for the quick patch.. I´ll try it out later :)
Food supply works good now as far as I can tell. Good job!
I also really like the new top tile half walls, though I discovered a minor issue with doors. When you place more than one half tile next to them, their door-texture fades while you can still use them as doors – they just don´t look like doors anymore.
And there´s a bug about raids not showing up sometimes.
