Appreciate the info.
After lots of trial & error the only thing that seems to somewhat work is to make each position coordinate entry in each formation "-0,0".
This way the number of units are still there but they all occupy the same spot. It works ok on the strategic map as each unit's animations are identical. On the tactical map when the single unit gets into melee a second unit emerges from the single unit stack to do the attacking due to the different attacking position.
It's not ideal as i wanted just a single unit graphic representing the stacks, but it's much better than seeing a big blob of unit models all clipping each other.
I have another conundrum that you could possibly help me with.
After looking at the sovereign talent that gives the iron ore resource to your starting city it was easy to make a new talent that makes more resources appear, named it Cornucopia, but i couldn't get the shard resources this way. Are they treated as a different type of resource?
If so, would i need a different instruction in the Attribute entry.
