MonoBehaviour Error

I have a game with 6 levels which is nearing completion which I recently switched from Iphone 1.7 to Unity 3.
Everything has been going smoothly until today. For some reason every time the game changes levels I get the following warning "The referenced script on this behaviour is missing. Then it says the error is at the monobehavior.cpp at line 1624.

Does anyone have an ideas?

 

Please can you report this as a bug (menu: Help > Report A Bug). There seems to be a related problem with Windows but I can't find anything similar for the Mac in the database.

 

As it turns out this Monobehavior warning is always there and does not effect the game. I was have a problem with my script which was compounding the error. So I have corrected my script and my problem went away but the warning remains. Is this a bug on the Mac that I should report?

 

I'm getting the same thing when trying to compile the Procedural Meshes examples. I get the same "The referenced script on this behavior is missing" and the error in monobehavior.cpp at line 1624.

This is with Unity 3 downloaded yesterday and the examples from here downloaded today. Pro license (upgraded from 2.6). I did let the 3.0 installer remove 2.6, as apposed to uninstalling 2.6 myself - if that makes any difference.

 

I have the same issue, and i solve it. The problem i has, was that i used ViewArea object. But in Unity 3.0 there is no ViewArea. U need go though all viewareas and delete monobehavior script, and add to this object Component->Rendering->Occlusion Area. I hope it will helps

 

I had this same issue, I had deleted a script from my project folder without removing it from an object in the scene. So I just deleted the missing script component from the object and the error went away.

 

This happened to me when I had 2 instances of the same prefab in different scenes and in one of the scenes the prefab was deactivated. When I edited the active instance (deleted a script component), I began to receive this warning when I loaded the other scene in the game. It helped just to switch on the deactivated instance and switch off again and the problem disappeared.

 

Hi I am new to Unity, although I was following https://unity3d.com/learn/tutorials/projects/roll-ball-tutorial/moving-player?playlist=17141 video and I copy and pasted the script to test it, and it doesnt seem to work in my solution tab under my file name it says load failed, and has a long number key, also the mono behaviour does show up in a hyperlinked looking word it is just normal text writing same with rigedbody and heaps more??
