Elastic Pitch - Stretch error @ mixdown


Ever since the update to 7.1.2 ,we got mixdowns with errors (dropouts/skipping audio)
when the elastic time or pitch algorithms are used !
Realtime playback is fine. Tried a bunch of diff. latency settings to no avail.

Anyone with the same experience ?
Got it in different sessions on totally different DAW’s all running N7.1.2.
