TOPs ropfetch_render stopped, node says complete but seq has missing frames. Dirty and cook claims complete. How do I make it check the renders and pick up missing frames?

[eldrich]

I left a TOPs network rendering some camera angles, but it's stopped with missing frames in one of the sequences (1-112 where it should be 1-144)
Dirty and cook returns done.

The caveat is I have 'Cook frames as single work item' on for post-processing nodes (ffmpeg and then some python in this case), when I deselect this I get all the frames and it picks up. 

How can I get it to check the frames, discover which are missing and pick up where it left off? 

 

OR would it be better to let it cook individual frames and then group the output by filename and push that into ffmeg?
