I'm still using the patch you have up. I haven't seen any new patches or so call mods. Unless only people supporting can now get them?
this is the error I get all the time:
KeyError: u'gna'
I know the issue. The issue is that the patch listed on Itchio does not have an updated Character identifier for the Great-Grandmother.
Opening the file with notepad and adding the following line to it will solve the problem.
define gna = (_("great grandmother"))
