Quaterions... Typo in blueprints?

No it’s not a bug, but hey hi it’s there.

So like… It’s meant to say “quaternions” in blueprints right? Instead of “quaterions?” Right? Do I start giggling or are these different somehow?

Thank you for your time.

Edit: Nvm it’s a typo lol.
I’ll leave this up for your enjoyment.
