Not sure if this is by design but I don't see why it would be.
I'm using 2.0.3 but it's been happening to me since I started using the program and I just never bothered to say anything until now. (This is talking with Quantize on)
Say I have a song. and I set all it's cue points. If I come back to that song later, and shift the beat grid ever so slightly, because I noticed it was a tiny bit off (sometimes it's just a millisecond or two but you can still notice the difference) so I shift the grid.
When this happens, I go to each previously set cue point, delete it, then reset it.
However, if I click on the cue point, and it snaps to this cue (which is now out of the beatgrid, because I've adjusted the beatgrid since I set that cue) - when I delete this, and press c, I believe it SHOULD now jump to the new grid point location (slightly forward or backwards), but it just stays where the previous cue point was set.
I hope this makes sense, hoping I don't have to make a video but I will if I have to.
Also, this just gave me a new awesome idea... Cue Point Beat Grid Adjuster!!!
An option or button so that when you shift your beat grid, the cues shift with it!!
