Grouping token Art Assets & Drift

Occassionally I like to stack multiple art items together like if something is dirty or submerged or broken I might group together the stacked images. Even if I set all the art images to "are drawings" and then group  they still seem to want to move towards the gridded corners individually so the illusion falls apart.. For example . Here is a cracked crystal  - the key to solving a trap in another room. However if I click and move the token with the arrow keys or just click and hold with the mouse and move it about the map a bit  - everything shifts and drifts and it ends up looking like this.  The three  images are  still  grouped"as one token" but that token has expanded in size and the individual assets move and drift  around inside it. I can only reassemble the three assets if i first click "ungroup"  If I select the group I made you can see it still highlights it as a single token so it;s not as though the grouping failed per se.  They are grouped.  Thety are just not fixed togetgher as a single assets seemingly. Why is that?  It's like the grouping fails somehow and Roll 20 just givesup and lets stacked images fall over and move of their own accord.  It's very peculiar and I'd love to understand what causes this and how I can stop it happening.  Any ideas?

Are you selecting just the one? or both? All of the below assumes the images are not already selected. 1) Selecting one without snapping to grid : alt+click on one of the images. Any movement will apply to that image only. 1b) Alternately, if the image to "Is Drawing" click on the image. Any movement will apply to that image only. 2) Selecting one with snapping to grid : Alt+click on one of the images. Release alt, then release the click. It will snap to grid for that one image (not the group).  3a) Selecting both without snap to grid : drag selection box over both images. Then click on group, hold alt, and drag to new position or hold alt while using arrow keys. Any movement will apply to both images. 3b) Alternately, if the image to "Is Drawing" drag selection box over both images. Any movement will apply to both images. 4) Selecting both with snap to grid : drag selection box over both images. Then click on group and drag to new position, or use arrow keys. Any movement will apply to both images.

A+B = Group AB, AB+C = Group ABC.   Hightlight grab ABC and move   = A.........B..........C I thought holding down ALT switched off 'snap to grid, allowing' for precise placement of objects.  I will double check and see what happens when I do and don't hold down ALT see if that makes a difference.
