Ok it seems fixed now but the previous problem is mentioned below: The "fix" I did is in the next post below this one.
So I'm working on a golf course and putting the final touches on it and I am adding some trees here and there. Then it seems they are not showing up but since its just one tree here or one there I am wondering if I am on the wrong hole or what so anyway I finally put a tree in the middle of the front T so it will have to show up then I save the terrain to a new file name and save the scene to a new file name then I click on the thing so the course is processed to be played like I have done 100 times then I copy this folder to the courses folder like I have done 100 times but the tree does not show up in the middle of the Tee. So unity or something course forge is no longer able to do anything ???
