I originally found the "Personality" mod as I was searching for a keybound Crawl mod that would work with Yes Steve Model. Thankfully this one does work with that!

I saw that this mod also adds a keybind to Sit as well, so I tried it out but unfortunately that one does not seem to work. The camera shifts down, but the player model does not take on the "sit" pose/animation.

If it matters, I'm on Minecraft 1.21.1, and this is the observed behavior with only Personality (+ Blueprint) and YSM installed.

Thank you in advance! m(_ _)m
