Ride obstructed by nothing?

[JoGo]

I'm trying to understand why I can't place this small ride directly on this flat surface.

There are no scenery items underground that could be obstructing the ride.

Any ideas?

If you have collision detection on it means the ground is not completely flat.

Or you want to place the ride to close to the edge.

Thanks for the response.

I figured it out with the help of the Steam community before the thread got approved (why does it take so long?). Disabling collisions doesn't work, instead you have to remove the water, place the ride, then place the water again.
