Setting Asset ID reference to instance on a different level causes reference to be lost on reload if asset is renamed.

When a variable of type AssetID is set to an asset on another level, the reference to the second asset is lost after reloading the project if the second asset is renamed.

Regression:
No - this behavior occurs in 4.13 as well

1. Open UE4 Editor (any project)
2. Add two new levels (TestLevel1 & TestLevel2)
3. Set TestLevel1 as the persistent level and TestLevel2 as a sublevel
4. Create a new blueprint of type Actor (ActorBP)
5. Create a new public variable inside ActorBP (AssetRefVar)
   • Set Variable Type to ActorBP->Asset ID
6. Add instance of ActorBP to TestLevel1 and TestLevel2 (ActorBP1 & ActorBP2)
7. Set AssetRefVar for each instance to point to the one on the opposite level
8. Save All
9. In the World Outliner, select ActorBP2 and rename
   • Note that when ActorBP1 is selected, the new name of ActorBP2 is set
10. Close and reopen the editor

Result:
When the editor reopens, ActorBP1 has lost it's reference and is set to None. ActorBP2 still holds its reference to ActorBP1.

Expected:
Reference is held after editor restart if the asset name has changed.
