I was actually trying to build something else, and came across this little bug. No need to self-check for functionality, as it does so for you.
I've not been much active lately... mostly just developing bots and such. I will try to post more. (Don't keep your hopes up.) And, yes, I know. @griffpatch (maybe his tutor account) already made one of these, which broke. I'm not kidding. Just a coincidence.
