Nuendo 11 & 12 Export selected tracks bug

Hello everyone,

i have a really strange random bug in Nuendo 11 & Nuendo 12.
My Session has more than 20 track, one of it is the IT-track. When i try to export them with selected-track to a .xml as referenced media with nuendo 10 compatibility, this IT-track won’t exported in both Nuendo 11 and in Nuendo 12. Nuendo just showup a dialogue that says: “The selected track types cannot be exported!”

This track is just a stereo track with no plugin, but with a timestretch. If I make the timestretch permanent, it won’t work at all. Same error. In a version before, i can export it, but i just copy audiofragments of another stereo track onto it and then it won’t work anymore.

Is this a general random bug for each nuendo versions or is it a bug by nuendo 12? I edited the whole project with nuendo 12.

Greetings JoDa
