Dear Tiago,

I use LyLuaTeX myself and sometimes I encounter problems similar to the one you
described. I do not know if this is a bug, but a workaround that worked for me
so far is to make the Lilypond code pretend there is an extra space underneath,
by using a markup that’s shifted by extra-offset. So for your “soprano”
variable could be amended to, for example:
soprano = { d’’8
\tweak extra-offset #'(0 . -3) _\markup { \musicglyph "space"} c''
\stemDown b'4 }
I know this may not be a perfect solution, but at least on my end the issue of
your incomplete lyric tie is resolved.
Hope this helps,
Yoshi
