Crap. I'll go fix that. I think I'll leave it as-is for now, since I don't know how putting out a new version will affect the submission and it seems unfair, but once voting's over I'll put up the fix.
I actually knew about the spelling! And then just... didn't spell it right, anyway! Another thing for next time.
Thank you so much for letting me know these things. (Especially about the fix!) It means a lot, and they help me improve.
