Mordent-8va bug in MIDI export

[sarraca]

Hello everyone,

I have been struggling with a bug in midi export for a few days.
On a piano part, the combination of mordents (rendered), and 8va (or 8vb, or trill...), exports a stuck note in MIDI which makes a mess with my work (see screenshots).
I can't say exactly what makes the bug occur (for instance, 8va are ok in that piece before mordents come in...) but it seems it comes from the rendering of the mordent (extension) as it also adds some strange velocity off MIDI datas...
Did someone else encounter a similar problem?
Is it scheduled for fixing? (I have the latest update of Sibelius 6.2)

I didn't find any workaround - except removing the 8va or the mordents... any idea?

Thanks
