fix collision on trees and other maps

Almost all blight games go good besides maps with tons of trees the trees can be like on the far right of my screen so i can barely see them and i still bump into them they are like twice as big as they are some trees have SUPER BIG COLLISION som doesnt have a collision at all you expect me to learn that ooh the tree beside the hill next to the pallet has collision ooh this tree in the middle of no where is slippery now this isnt a big probem but its annoying as hell to waste 5 rushes because the last 2 "hits" a tree when your not even close... its so damn annoying to glide on rocks trees and stuff probably had 100000 easy downs lost becasue a tree has double the collision it should
