GameObject.tranform.position is null

I had a full project running and working up until yesterday. I added only one object to my scene and later removed it and re-saved the scene. I made no changes to my scripts.

Now, I keep getting this message:

NullReferenceException: Object reference not set to an instance of an object StartScript.OnMouseUp () (at Assets/StartScript.cs:14) UnityEngine.SendMouseEvents:DoSendMouseEvents(Int32)

All I do in this line of script is finding a gameobject and setting its transform.poistion= new Vector3(0,0,0); I keep getting an error that the transform of the object is null, but this object is still part of the game. I never touched it!

Do you know how to solve this problem? I'm working on Unity3D version 5.

Are you sure you find the Gameobject? have you chekc if it was returning null? - Matriac
and can you please post your code where you find te object and set its position? it would help for finding your error - Matriac
Post your code so we can help - JoRouss
How are you finding the GameObject? by tag? by name? by Component? by Layer? Maybe one of these has change/deleted on the gameobject you are trying to find. - Rana
Actually ... a Vector3 can not be null. In Unity Vector3 is a struct which is a value type, only reference types can be null (unless ofc you wrap it up in a nullable, but thats a whole other story) - yes

There is bug in Unity5 when you make a build. The tagging system isn't working well, all I had to do is to recreate my Tag list manually.
