Oh well.
"Missing mesh" means those meshes can't be found where they're supposed to be. They could've been installed to the wrong folder, or there's a conflict somewhere. Check the compatibility list for Better Cities in this threadif you really want to use it. You can also ask and post your pictures there and you will get help from the mod makers or other modders. It's quite an advanced mod though, with lots of things that can go wrong, so you might want to skip it for now.
