It seems that the way localization files overwrite each other was changed in the latest patch, at least where provinces are concerned. I loaded my total conversion mod and the names of the provinces had reverted to vanilla; when I renamed my localization file from "zz_province_names" to "AAA_province_names" so that it overwrote the vanilla Text1 file that has all the province names, the issue was resolved.
Can other people confirm this? I don't think it would affect most mods, but for total conversion mods or other mods that replace vanilla provinces it could be a minor issue in updating.
