Right, don't fix any bugs, don't make any changes, someone might like it the way it is.

And any changes can be modded anyway. (Well, except no one seems to have come up with a way to mod this, but we'll ignore that.)
So forget patches, except maybe new content, but that can be modded as well and maybe someone likes only having the original nations...

Sarcasm aside, I don't think this is being raised as a balance issue. It's not a matter of nerfing something that's intended but too strong. This is something that doesn't work as expected or, apparently, as intended. It's not a nerf. It's a fix.

And why can't the SP players make and use the mod? It's easier for one person to agree on a mod than for a whole group.
