Selecting foliage by using the “select” tool from within the foliage panel causes the editor to crash if the selected foliage is not highlited among the already placed foliage, i.e:
If I check tree from the foliage list, and attempt to select a tree on the landscape, I have no issues. If nothing is checked, or say, a rock is checked, and I select the same tree as before, the editor crashes.
