Hold previous bug failing to render


#1

Hold previous is not working on every next of hundred frames.

for example i got frames 1-180, 221-380,421-480

it render frames 1-180 —> until 201 but it gives error loading frame 201 and so on on next frames of hundred where frames are missing. In this case there is errors on 201, 401

osx version, not sure about win and lin
