Crash after moving an Object and pressing Ctrl+Z

I placed an Object (City House 2 Towers), deselected it, when trying to zoom out realized i was still rotating the Object, tried clicking into an empty Area, to deselect it, which in turn reselcted the object and instantly moved it to where my mouse was. While the Object was still selected, i pressed Ctrl+Z to move it back and the Program Crashed with the message Popup "Fatal Error"
