So in Tharmachati we have an exhibit with a bunch of platforms over the guests the binturong are supposed to climb on. But we're having a hard time making them use the climbing structure, because essentially the platforms aren't recognized as traversable area, only climbable area.
As you can see, this is one of the platforms. When looking at the traversable area, this is what we get.
None of the climbable platform pieces are traversable, and even adding a layer of planks on top of them has no effect.
Whilst when I put the climbing platform on the ground, all of a sudden it is considered part of the traversable area.
Anybody got an idea of what I'm doing wrong here?
