I know it's hard to add in the singular they when you've already written so much without it, but I really appreciate that you're doing it anyway. It means so much to me as a nonbinary person and long-time fan.
I can't send in every single instance of incorrect pronouns because there's been a lot. From what I've seen, the bug seems to be turning many/most instances of "them" into "their" instead. Hopefully that means it will be a simple fix, but I don't know the second thing about coding.
(I do know the first thing is that the curly brackets must each have a friend or things go very badly.)
