Error while creating collection

[ThomasH]

I want to create a sprite collection spanning over 4 atlasses containing 4 images of 1920x1200. When committing, I get the following error:

Code: [Select]

MissingReferenceException: The object of type 'Texture2D' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

Any help appreciated

Its an incompatibility with Unity 4.1x, fixed in tk2d 1.92 + patch 1.
