You'll have a small handful of crash reports from a few minutes before the creation date of this post.

This is a quick summary of what happened:

I restored a model tab after my session had expired, so was redirected to a Google/auth0 sign in page. I signed in and was redirected to my user page. I browser ed enough times to get back to the model I was previously looking at and was presented with the model with an error overlay. Any other page loads showed what I wanted in the background with the same error overlay.

Workaround: I signed out then signed back in and everything seems to be working normally.
