Beta 17
When I have the render set to single frame and do a Generate All Partitions Locally, I get frames 0000 and 0001 for each partition.
When I make partitions with Deadline, I correctly only get the 0000s.

This is As Designed.
A vicious bug in PFlow prevents us from creating a single frame with varying random seeds. Somehow PFlow figures out we intend to render one frame and refuses to update the system no matter what, so the result would be multiple partitions with the same seeds. Thus, for local rendering, it always does two frames in a row to ensure the seeds will be incremented correctly.
We could not find any other workaround. This will be documented (if it isn't already).
Yeah, we’ve seen that bug, where you change the seed and it doesn’t invalidate the particles until you change frames, but can’t you just render 2 frames but only output the intended frame? Or post-render cleanup the output by deleting the 0001 files?
Seems we’re going to be deleting a LOT of 0001 files manually otherwise.

What I might do is save both with temp. names, then rename the one to the real name and delete the other. I want to avoid killing a frame that already existed (right now, it would actually overwrite the other frame if it existed, which is not too good either).
You’ve brought this bug up to ADSK? Seems like one of those things that you’d want to change in Krakatoa once they fixed PFlow (if ever).

Of course not. Nobody there is touching PFlow, chances for this to be fixed are minimal, and we need Krakatoa to work with PFlow in Max 8 and 9, not with Max 2011 ;o)
So we do what we can to work around all the funky things that happen.
