All the same, I'm one of those people who are not good at editing files, so even though it is clear Bhruic has done a very impressive job (which Firaxis should have done in the first place, but never mind), I don't want to install his patch because
1. I am not sure how to do it correctly,
and
2. I'd probably have to uninstall and reinstall the whole game when and if a new official patch emerges.
That is to say: If you are good at editing files, then you are presumably fine. If not, then the trade weirdness and a few other things can be quite annoying. Still, a lot of things have been very much improved with this patch. (Ignore the screams from the multiplayers.
