It would appear the Render tab and the New Player ignores the Timescale value and determines the length of the sheet by its Tempo value, thus cutting the sheets short if Timescale>1. If you download the song and view each individual sheet, you will see that the notes are there and plays perfectly fine in the Sheet tab.
