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?
