Anyone else getting crashes if you hide a prefab then try to switch levels? It crashes like 50% of the time with:
Assertion failed: [File:D:\Build++UE4\Sync\Engine\Source\Editor\UnrealEd\Private\EditorServer.cpp] [Line: 1971] /Game/Maps/testmap.testmap still around while trying to load new map (Object is not currently rooted)
