Staff misaligned in EH to OB instrument change

Anyone else having this strange issue of staff misalignment when changing from English horn back to Oboe 2? See screenshot.
It’s the first I’ve seen of it.
I tried changing the length of the note, dynamic, etc. etc. but it’s still there.

(I faked a fix for now by adding a note at the end of the system and hiding it so that the instrument change happens on next page, but luckily Oboe 2 didn’t have to play until next system)

We have seen this once before, and I believe we have fixed it since Dorico 1.2 was released. Please attach here or send me via email the project (together with a link to this thread and details of where the problem occurs) so I can verify that it’s definitively fixed.
