Height change

I’ve made a map via “intermediate” tool - custom layout.

I’ve change height of all map to 0 and changed height of starting TC to 0.

The problem happens when starting with other mod. It get “scar error”. (CBA-mod replace TC and spam units)
If height is not changed - everything works fine(with or without mods).

Its’ very very hard to create map from scratch.

So mb someone understand height and what should it be, should we create map with “painting” for flat maps? or when start positions should be added.
