Render is a a lot cheaper than Vercel, and the forum has quite a lot of cron jobs that are more annoying to setup using a serverless architecture. We also had a good experience using Render when we built Forethought's new website last year. We're still using Vercel for all of our other sites though (at least, for now).
Should be fixed now! It wasn't actually Toby's fault; it was a preexisting bug caused by using the markdown editor.
