Working on parts for my enormous Wagner project: In engrave mode everything looks great, I press print and the print preview (and resulting PDF) have decoupled some (not all) of the multirests. See screenshot:
If I now go back to engrave mode, the multirests have decoupled as per the print preview. I can force them to reappear by selecting the beginning and end of a system and clicking the ‘make into system’ button. But as soon as I press print again, it flicks back to separate bars as above.
