Sometimes Layers´ output stops

Sometimes Layers´ output stops.

To bring them back to work i have to switch to a different song and back.

Cannot reproduce, we need a lot more details. Can you narrow it? What instruments, what configuration, many or few Layers , MIDI device etc. Is there a specific situation when this happens? Does Transport run (play mode), do you have Part triggers? Haven’t had that yet, so we need to know how to reproduce it.
