Alt+Drag creates bad clone 4.8.1 problem

When I alt+Drag a object, and hit it with anything. ALL copies of it get affected.

If I drag from the content browser one by one, those get affected individually.

When I went from 4.7 to 4.8 this started happening. I had a project that worked perfect, and now all objects i cloned using alt+drag have to be replaced.
