Crash when opening a level with skeletal mesh asset from the map copied to the clipboard

Crash when opening a level with skeletal mesh asset from the map copied to the clipboard

Description

Navigating to a level with a skeletal mesh asset from that level copied to the clipbard from the world outliner will cause the editor to crash. This can currently only be reproduced in the TM-ContactShadows map in //UE4/Release-4.13 by copying one or all of the cloth skeletal meshes in that level, opening another level then opening the contact shadows map again. The cloth assets are not checked into main branch yet, but the issue does occur there as well. Copying other meshes from that level like the demo displays does not cause a crash. Another user is seeing this same callstack when closing the level but I havent been able to repro that way.

Steps to Reproduce
  1. Open QAGame in the editor.
  2. Open TM-Contact shadows (Content needed to repro is only in release-4.13 for now, cannot repro on other maps)
  3. Select a cloth asset in the level
  4. Copy the asset in the world outliner
  5. Open a new default level
  6. Open TM-ContactShadows **FROM CONTENT BROWSER**

Result:
Observe a crash as the level is loaded
