Sorry to bother you, have you turned off Patreon purchases? I can't find where to buy it, but I can see other creators' buying options (sorry, I'm not a native English speaker)
We're still on Patreon and people are still supporting us there! I'm afraid you'd have to ask Patreon for help if for some reason the site isn't working for you.
Are you under 18? Our Patreon is for adults only and if your account doesn't let you access it that may be why. If you are minor do not use a different account to gain access to adult content!
