To reproduce:
1. Download the Tower Defense Toolkit asset bundle
2. Try to open the "TDTK_Demo_Menu" scene
The editor will crash on OSX and freeze on windows. On windows this message appears on the editor log before freezing:

The file 'C:/Users/Benas/Desktop/Unity Projects/Asset store bash project 2/Assets/TDTK/Scenes/TDTK_Demo_Menu.unity' - 'Assets/TDTK/Scenes/TDTK_Demo_Menu.unity' is corrupted! Remove it and launch unity again!
[Position out of bounds!]

When crashing on OSX, this is the stack trace:
