Another update (Patreon)

First I'd like to apologize to my tier $15 patrons. When I first started my patreon I only had $1, 5$ and $10 tiers. When I decided on making my $15 tier I'd forgotten update all the old art. All older rewards have been update to include $15 tier. Thank you for your patience. I didn't realize that this was an issue until now.
