Losing elevation data when switching to another scene and then back

[edoreld]

Pretty much what the title says. I'm using Wall Height and setting different walls around objects in my scene. Then, I set the elevation using the brush for the space between walls. I test with a Player token and it works perfectly, but when I switch to another scene and back all elevation data is gone.

As a workaround, I can save the elevation data and load it every time I load the scene, but would rather not have to do that if possible.

I'm not using Levels
