OK, thanks for explanation! Actually, I've menaged to solve my problem by entering hidden notes with unHidden slur in separate voice. Now the tie refers to the right notes and appeals to my sense of aesthetic - despite colliding with an accidental (take a look at the attachment).

Janek, I'm not a student of Politechnika Warszawska - neither former nor present. I'm a former student of Akademia Muzyczna w Gdańsku :)

Best Wishes

Yes, i do think that it will make more sense to rewrite tie code
bearing in mind all bad tie cases instead of fixing the issues one by
one.  Besides, i suppose that marking this as critical will have only
one result: next stable release will be postponed for 3 months or so.
It won't make the bug fixed immediately, nor even soon.

Yes.  The bad news is that i won't have time to finish it until
summer.  However, if there's anyone willing to finish it, i can share
my results and provide some guidance.  The task requires aesthetic
sense and analytical skills, and i estimate 40 hours of work is needed
to finish the tie analysis - no idea how long implementation will

Bottom line: find someone to finish tie report and implement it's
conclusions (or pay David to implement them - i will add €50 from
myself if this is done before May 15).

i hope that didn't sound too discouraging :)

PS Karol, are you a (former) student of Warsaw University of
Technology, Faculty of Electronics (Elka)?
