Application.LoadLevelAsync ArgumentException

Hi all, every time I load my main level, I get about 160 of these errors


From what I can see, these seem to be kicked off my the Terrain / Tree system that comes with Unity. No other scene in my projects has this problem when they're loaded via Application.LoadLevelAsync. I was able to narrow the problem down to the trees simply being defined in the terrain system -- they don't even have to be placed on the terrain to throw the error.


Has anyone dealt with this before or knows how to get rid of these errors? I'm preparing a sample project to submit a bug because no way should this ever be happening -- and it wasn't happening in Unity 4. But I wanted to know if there was something I was missing.

 

i am getting them easily - add a tree to a scene and load it (even in editor)
