I've updated unity to 4.1 and i am getting this exception
MissingReferenceException: The object of type 'tk2dIndex' 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.
tk2dEditorUtility.CreateIndex () (at Assets/TK2DROOT/tk2d/Editor/tk2dEditorUtility.cs:215)
tk2dEditorUtility.RebuildIndex () (at Assets/TK2DROOT/tk2d/Editor/tk2dEditorUtility.cs:60)


i can't use anything from the plugin because of this.
i get the same exception when rebuilding index
i have the latest 2D toolkit 1.91 final

What happens if you shut down Unity, delete the index, and restart Unity again?

This happened to me too.  Same version of Unity & 2D Toolkit;  when I click on a sprite in the scene it performs a "Rebuilding Index" over and over ... like in a loop and sometimes it does it a 2 or 3 times and then gives me the MissingReferenceException error above. I'll try deleting the index as you recommended and report back..

Searching in the folder reveals "tk2dIndex" is a C sharp file... I'm assuming not to delete that... My guess is that  "-tk2d.asset" is the index file...?   Anyways my folder doesn't have one; the back up I made before the 4.1 upgrade does; perhaps that's why it goes into a rebuild loop?  I tried installing 1.92 beta and still having issues... I'll try to install from the unity store one more time then I guess I'll have to go back to 4.0. :(

UPDATE 1:

It appears if I manually rebuild the index it'll delete the "-tk2d.asset" file, throw the exception ... and then complains it can't access it because it's destroyed.  (haha).  Another one isn't generated so now the project is left without an index file that can no longer be generated.  I manually copied the index file from my back up which is fine until I add something and it goes to Rebuild the Index again.

UPDATE 2:

Re-installed Unity 4.0.1f2 and so far everything appears to be running normally.  It generates a new index file without exceptions.

Same here. Even happens in a fresh/empty project.

Create Project
Import tk2d
Import 1 PNG
Create SpriteCollection
Commit -> The aforementioned exception comes up

Yeah managed to reproduce it.
Really annoying as it was working in the last 4.1 beta...

And... I have a fix.
I'm testing a bunch of stuff to make sure everything works, and a patch will be ready shortly for both 1.91 & 1.92.

Hello i just bought 2D Toolkit today but couldnt make it work because of this problem. I cant wait to start with my project and i know sometimes it can take a while to make patches appy on unity asset store. So if there is a way to fix this problem without applying a patch i would really like to learn it. Thank you,
Oguz Tecimer

That bug caught me off guard - I usually keep on top of the Unity beta releases, making sure things haven't broken. I never saw this one until it was too late, though.
