Hierarchy completely blank

Hi

Project just started bugging, leaving me with a blank hierarchy. I tried restarting the browser.

Only affecting one scene right now.

Any thoughts?

Any errors in the browser console?

Yes, a lot :smiley:

2 of us have the blank one.

I restarted the computer, and now we’re back!

Weird.

Super weird. Glad you are back though
