Sometimes when performing an export audio mixdown on heavy projects with over 100 channels of audio and vsti with a lot of UAD Plugins / Waves / Sonnox etc… the action results in the progress bar not updating while the processing begins. While it seems like Nuendo is crashed, it is infact still running and performing the audio export. However in some cases it is unclear, since export takes a long time and the user wonders if Nuendo is in fact going to finish the process.
Please check if this can be fixed on the next round of updates.
Thanks
