masks are not automatically saved in workspace dir even though the segmentation is correctly done

First and foremost, thank you so much for your very impressive work in the field of interactive semantic segmentation. Results are amazing and I love how I have control over fixing things by multiple time front propagating or propagation.

My question is, while the segmentation of one object is correctly done for the full video, the masks are not automatically saved in workspace dir. Do you know what has been the cause?
