nat (without full stop) does not work in playback
New Ideas : Sibelius Feedback Community 2016-09-26
Summary:
In a string part after the indication tremolo, nat does not return the playback to a non tremolo sound. nat. with a full stop (period) does as does the full word naturale. pizz, con sord and senza sord all work without a full stop and so although strictly speaking nat is wrong (being an abbreviation it should have a full stop) it is inconsistent with how other markings work. I found this while using an old file created in in an older version of Sibelius so I wonder if this bug has been introduced recently and wasn't always there.
