Discourse v3.2.1
Had a request for including tags for Post notifications to Users to include the Topic Tags.
Felt like it would be a slam dunk based on Customizing specific system email templates and %{optional_tags} with the User Posted event.
I added to the Body and the user started to get translation missing errors instead of the text body in the email. The user is not using any translation preferences so seemed to trigger some unexpected case in the notification processing.
Went back and added to the end of the Subject instead, but then the Category was dropped and tags still were not added to the Subject. Unsure if I hit a formatting limit there.
Is there something that I am missing about using that specific formatting token for Topic posts and replies?
