So I started to upgrade a number of scores I had already done and I discovered
the following excerpt which does behave weird. It is in the alto-part of a
four-voice a-capella choir-piece which in one bar is split. The lyrics however
are not handled correctly, due to the fact that the alto-part is completely
gone, but will be taken on in the next bar.
If I reduce the excerpt to the offending part of the bar I get an error
indicating that the alto-part is missing, although is printed. strange
This behaviour is also in version 2.12.2, earlier versions I cannot remember
if this was already in place.
