I have slick theme set as my [current theme]. Everyday (after about 20-24 hours) I come back to the forum page it returns to the Persona[default] theme.
The weird thing is in Appearance > Themes it shows Slick Theme is the current theme even though home page shows Persona. The only fix is I have to keep pressing Rebuild & Restart button.
Please share more about your setup. Are you running multiple instances?

I am running it on Heroku Hobby Dyno. I followed the setup instructions on
I don't think it's the cache I tried on multiple browsers and devices.
Installing plugins and themes doesn't work the same on heroku as it does on other servers. You can't just use the ACP to install them because of the way heroku resets. Instead you must install the plugins and themes before pushing the code up to heroku.
This is why it shows that your theme is activated. The database is persisted across resets of your heroku server. But since the built assets directory in the git repository were created under persona, it resets to that.
