@a_5mith, giving it a go now.
Sorry for the late reply. A weekend of drinking with friends, and work is kicking off in full swing with the college kids returning. Makes things fun - yet hectic.
The forum is now displaying a "The forum has been updated to the latest version" overlay in the top right - when I haven't updated anything. This issue continues. I went ahead and made sure that Cloudflare wasn't caching anything, as I use it for DNS.
Ran nodebb in dev - seeing no alerts. One warn that the action:app.load hook is deprecated - but the rest seems normal.
This doesn't occur all the time, but seems to be the culprit.
