Understood. And I actually have experienced it here on meta.discourse.org back when I set up our site in March. I was searching on Google for information about the Slack integration settings, clicked a link to a topic, and ended up with a mostly blank screen with the title header repeated several times (see second screenshot in my original post here). At the time I worked around it with Google Search cached version and then haven’t experienced it since then. And I could visit other topics and the home page just fine.
So strange.
I’ll keep scratching at this and definitely report back. With any luck, maybe it is resolved somehow with the beta3 update. 
Lastly, we are really really happy with Discourse and how quickly our community has been taking shape in just 6 weeks. I’m inspired and can only dream people will say the same someday about RedwoodJS once it has the time to grow up a bit.
Thank you.
