Why do we use themself on the UT wiki but themselves on the DR one?
Previous discussion for reference:

TLDR: It was "themself" on UTW, but when Deltarune came out, the spellcheck that Kocka was using while writing the new Deltarune Wiki insisted on "themselves", so when he and Gil wrote the Deltarune Wiki Manual of Style, the line saying to use "themself" was changed to say "themselves".
The linked post is the community vote where they decided to keep "themselves" on Deltarune Wiki.
Here we go again…
