C12 flatten arrangement bug: audio events are missing/cut away

Hello there,
flatten arrangement does not work properly when you’re dealing with a project which has different tempos.
Here a video to explain. The first half shows the issue, the second half shows how it works, when there is one tempo for the entire song:

Steps to reproduce:

  • create an adio track and put audio on that
  • create an arranger track and add arranger events to divide that audio event into different sections
  • create a different tempo for each arranger event
  • create an arranger chain with random order
  • flatten the arrangement

Here you can download a testproject created by myself, to test it for yourself.
