Running MIRROR Command on this block as is without the Flip Action works fine here.
Nothing unusual shows up as does in the Block on the left that was Mirrored in your drawing file.
The Flip Action is a natural progression for that block so that you do not need to invoke an additional Command to use this as you would like.

Kudos + gladly accepted if you are feeling magnanimous
Yes, I did not see any anomaly with the Block as is.
RECOVER or AUDIT the file that contains the Block and see if it cleans up for you.
And post your second block as well.
I've done both audit and recover. I still see the problem. If you can see it working fine then could it be something to do with some sort of view setting? As far as I know I'm using default settings for most things (apart from toolbar layouts, snaps, etc)
I've attached the file with the other block in it.
Has anyone else tried this? I still have the issue that the objects jump away from where they're supposed to be. I can synchronise the positions of the objects, but it seems like I have to do it every time I open and close a drawing.
First off, I would ask if you are asking the block to be visible in a new scale, and then moving it in that particular view? I think one feature of dynamic blocks is that each scale representation can be moved independently of each other. I am not sure if AutoCAD has a variable you can turn off to disallow this behavior. I am also not sure if being annotative doesn't play nice with the flip feature. I had issues with the flip feature and scales/stretches awhile ago, and resorted to manually mirroring the object instead. I suspect that if an object in one scale is to the side of itself when in another scale, then to mirror it over its centerpoint in the one scale will cause the shifted one to mirror as well, to a point now on the other side of the mirror point, yesno?
