All patterns disappear, which way to undo?

So it’s happened a couple of times, recently about 15 minutes ago, where all trigs on all tracks in a pattern disappear on my Rytm.

This time I had three patterns, no saved kits, “Kit” started blinking, and then it all went away (in the current pattern). I’ve had this happened before, and if I remembered correctly from the previous googling, it should be FUNC+PLAY to restore everything.

Someone please help me with this, just so I know for sure what to undo the next time.
