I went through the 31.02 entity file and fixed the capitalization for the nobles of all the races. It beats doing it yourself. There are no other changes to this file, so if you have other mods that add reactions or whatnot you'll have to add them back manually. It was made for 31.02 but it should work with 31.01 just fine.

To install this fix, copy the text file within the archive into your [Dwarf Fortress]/raw/objects folder.
