I see following errors in editor build 19 !GetPersistentManager().IsStreamLoaded(metaDataPath) UnityEditor.DockArea:OnGUI() Asset import did not unload metadata path. This will leak memory. File a bug with repro steps please. UnityEditor.DockArea:OnGUI() I am not sure about repro steps but it is probably related to my play with sprite editor to slice images.
I have the same error in 4.6.1f1. I'm just trying to change a sprite's pivot point in the sprite editor, and when I hit apply, it gaves me those two errors.
