I hit the bug in X8

[asik1]

I recall it was raised before but strangely I hit it just as I finished a project.
I did a bit of house clean and deleted few files from my output folder.
Than I reload a version of this project just to find that B/W missing segment. This segment is made of a slow-motioned clip with NB background generator. The original clip is still intact as I use it in another part of the project .
I can only guess that the culprit is that the VSP did not save the slowmotion data hence could not recreate the segment.
I dug into the VSP file and noticed it do not have the NB background generator data also.

That B/W culprit is now in all of this project versions ( and a smart package test I did few weeks ago) , I guess I deleted a rendered file that was created in the process of constructing that segment.
