I recently updated to Unity 5.3, and the Playmaker Hash Table Proxy seems to break during runtime making any sort manipulation fail. It greys out the inspector and throws back an error.
"Expected top level layout group missing! Too many GUILayout.EndScrollView/EndVertical/EndHorizontal?
UnityEditor.DockArea:OnGUI()"
I've been able to consistently recreate it by just expanding the PreFilled data menu on the Hash Table Proxy, then running the game.
But if the PreFilled data area is collapsed, then you run the game, it works fine. It's just whenever you expand it, whether before/after running game that the table breaks.
I also tried a fresh project and got the same. Here's a screenshot!
Any ideas?
