This bug removes foliage from a level when the Component Blueprint is compiled.
Switching the Foliage type asset to another component will cause the issue to stop occurring.
The Component Blueprint does not need anything added/changed. Clicking compile will cause the bug to occur.
Present in 4.17.2 CL 3658906, 4.18 CL 3709383 and 4.19 Main
Result: Foliage in level will disappear in the editor window, the Foliage meshes will still appear in Play mode
Expected: Foliage will not be affected upon compiling the Blueprint
