I have this problem with .NET Reflector that when I try to export a dll file (even if I didn't modified it yet) it doesn't finish exporting it and it just freezes, I can't close the window, and if I click stop it stops exporting but doesn't let me close the window neither. I have to close the program from the task manager. Trying to export unmodified dll, stops at LevelStorage.
This is the dll file: Assembly-CSharp.dll
