If that's the case then it's probably intermittent. The difference between 15, 16 and 17 is actually quite small and no changes to the guider or sequencer were made in any of those. Mostly it was logging and addressing a fast fame download issue.
It's up to you to try .17 again. I will say that 15 and 16 have a fairly large flaw in them when taking frames in rapid succession which was addressed in 17.
I'll attempt to reproduce this locally as well as it seems we received about 3 reports of this same issue within about 48 hours. Which is odd since .17 has been out for a bit now. Not sure what else could have changed.
Thanks,
