ProBuilder - "DestroyImmediate" Bug - Experimental (Meshes as Assets)

This may be a known issue, but I have an editor extension that clears the active scene of created objects. When deleting an asset that has a ProBuilder component on it, I receive in the console an error about calling DestroyObjectImmediate without the boolean flag to allow destruction of assets when using the Meshes as Assets function. Obviously, this is the proper way of destroying scene objects within the editor, but I'm guessing ProBuilder is not including that boolean flag.

The only reason I personally want to use the Meshes as Assets function is so that I see mesh preview images in prefabs I've made out of ProBuilder objects. I wonder if they're working on getting that to work..
