It's come to my attention that SubscribeStar does not do what Patreon does, in that higher tier subs don't automatically have access to lower tier posts, they need to explicitly have access, meaning that some older posts are actually inaccessible if you're subbed to the highest tier. This is bonkers and really bullshit, but unfortunately I'm just about to be busy for the next couple of hours [it's why I posted this week's art earlier than I usually do]. As soon as I'm able, I'll go back through the archive and fix all the tier access tonight.

Edit: It didn't take that long, it turns out. Everything should be corrected.
