After upgrading Peril, unable to send markdown to new issues

Good evening! I upgraded to the latest Peril (from whatever was on master January 5th, Heroku won't give me the initial deploy sha) and it's no longer posting comments to GitHub. Everything looks fine in the logs and it does _say_ it's commenting, but it never shows up. Here're the logs from a request:

Hmm! I took a look through the recent issues on Peril and Danger.js, as well as the changelogs, but didn't see anything that could explain it. I'm going to try looking into it more tomorrow, let me know if this rings a bell. My settings repo is at https://github.com/ashfurrow/peril-settings and here's the rule that was executed in the logs above: https://github.com/ashfurrow/peril-settings/blob/master/rules/all-issues.ts. Thanks!
