When I added a bunch of trees to the map, it became unplayable. I took half of them out, and i was ok, but units could walk through the areas I meant to block off with trees, so I put on the 2x2 with small ground pathing blockers and laid a couple thousand out. I ddn't think they caused lag, but apparently it's a lot. I'm working on reducing the amount by a thousand or so, but I don't know if it will help... there's still so many. My question is could be the pathing blockers/trees or do they really not take up that much space?
