I heard back from SubStar about the bug on my page! (Patreon)

They found the issue. It's a rare bug that happens when you exit vacation mode manually sometimes. I gave my confirmation that I do in fact want billing to resume on SubscribeStar and they said they will reactivate it shortly. I'll let you know when I get confirmation that it's fixed. When that happens, I'll post the entirety of Star Thrust's edited version there (the first 100,000 words is done, audiobook will record soon).
