the decoratives on this map didn't use enough space to the player base.
And since the last biome update introduced some non-actors as decoratives, that lead to actual bushes spawning inside/ too close the cc in some cases.
This does fix the problem reported by player of 0ad: https://wildfiregames.com/forum/topic/73619-tutorial-map-woman-overlapping-stone-mine/#comment-484761
This also removes the standard decoratives around the cc as I think it looks bad to have grass patches on the stone tiling.
