[0.18.X] Resource map preview behaviour

[Linver]

Hi to all. As described in the title:





This is a modded resource. Hovering the mouse on the resource, in the map, change the visibility of resource patchs, some resource patch appear.
I look many times the definition of this resources and I don't think this is the problem:

Is (almost) identical with the definition of crude oil, and the sprite priority is on "extra high", so should be not a problem of z-axis.

It's not z-axis problem, it's "checkboard pattern" problem. Set map_grid = false (that's the key difference between your definition and crude oil definition)

Oh, thank you for the tip, I can't deduce this from the documentation because map_grid haven't a description.
