Bug: PSD master playback status disappears after pressing update with another tab open in the same frame.

I was not able to replicate this.  Does it continue if you save, deep clear, and then re-open the show?

Ooh, I shouldn’t deep clear during a rehearsal period right? Will any data get lost?

If you save your show, then deep clear, all that will  be lost is the persistent storage (temporary memory) on the desk. You will need to re-open your show file after the deep clear.
