Problem with do no stack

Hi guys,
I have 3 different pieces with the trait “do no stack”.
These pieces are distributed randomly on the board, but one must always be below the other two. When I start a new game, this piece is OK, below. But when I save and load the game, the piece now is up other two (sometimes in the middle, partially covered by another piece). How do I resolve the problem?. Thanks for advance

Simplest way would be to create map layers and assign the bottom piece to a lower layer.

Ok, Dr. I’ll try

Thank you Dr.
Problem solved! :smiley:
