preventing piles of character tokens on a cell

Is there a way to prevent a character token to move to a cell occupied by another character token ? so they never pile up ? and only allow a gnome to coexist in a cell with a larger character ?

I don't believe anything like this exist but i think it could be written with a custom API script - though that could get complicated.

It would probably break or be impossible, right now in the netcode people don't actually see tokens all in the same places, there are tons of out of sync examples every single time I run a session.  

Players will always see their own token on top, unless they have more than one there. It wouldn't be too hard to detect the case, and there are various ways it could be handled, such as resizing them all to fit in the square together, or moving each of them to a corner of the square.
