StopTheMadness preventing Cloudflare "verify you're human" from working?

This has happened to me on two different sites in the past few days, and hasn't happened in the past.

I've been getting stuck on the Cloudflare human-verification page...if I click that I'm human, it refreshes and shows the page again.

In both cases, disabling StopTheMadness allows the verification to work.

I haven't had a chance to test which option is involved yet.
