Ok, so I've been working on my forest for almost a year. I just hit 40 obstacles, with 39 being where I want them. The 40th *might* not get removed because its a headstone. My question is, if I'm sitting at 40 with a gem box, a Christmas tree, and 2 headstones can any more new obstacles spawn? Do those 4 unique obstacles count?

If more can spawn, how many more?
