$20 reward mix-ups (Patreon)

Some of you have been noticing that the $20 reward keeps changing and for that, I apologize. I thought if I could make it so that I could limit the number of patrons that get sketch requests from 5 to 10 to whatever, it would be less work for me and afterwards, I could "reset" it for a group of new patrons. Turns out that's not possible. At least, not without deleting your pledges. And explaining that patrons that donate a month only get one sketch request from me didn't make it easier or fair. So I'll just say "screw it" and say that patrons, past and present, who pledge$20 a month will get a sketch drawing from me a month.
