Missing Scripts in AssetBundles

• I create a project "A", with a script "MyRotate.cs".

• I export only "MyRotate" script as package (.unitypackage).

• I create another project "B", i'm importing the above .unitypackage.

• I create a gameobject and add MyRotate as component.

• I export this gameObject as AssetBundle.

• In project "A" i'm trying to load the AssetBundle above. I obtain the gameObject, but the component are "None" and show "The associated scripts can not be loaded.";

Now, i understand that AssetBundle can't contain scripts. But in this case the same script it's already present. It maybe simply have some 'internal' reference that are different.

How i can reassign/fix them at runtime? Thanks for any feedback.
