Adding a tie from grace note to note goes wrong way at times
In this picture (sample file attached) select the grace note in red and press + to apply a grace note. The tie goes to the note before it. The third grace note is required due to the second note tie not working properly. There's another bug report for that already.
Workaround is to change the pitch of the second grace note while applying the tie.
