Problem with straw and grapes

[Ealloraaa]

Hi everyone, i'm working on a map and during the test i discover that in some area of fields straw doesn't appear. Any suggestions? I put a link for the image. https://imgur.com/a/yRegOHi

The second question is about grapes. i would like to have grapes in some fields (no owned by the player) but the result everytime i try something is grapes at the final stage of growth for all the time. Are there a way to make them to have the circle of life even if i'm not the owner?

For the straw issue:
Looks like you need to run the script in GE to create the ground collision map.
Change will than be active in a new savegame.

For grapes:
I know there a pre-placed grapes on the maps Clarkson and Lands of la mancha. But I can not remember if they change status or not.

Already try with the script
