Instanced Static Mesh Actors created with (new in 4.20) ISM Merge tool do not immediately appear when duplicated.


Confirmed in 4.21 Main @ CL 4374913

Steps to Reproduce
  1. Drag 2 or more of the same meshes into world
  2. Select both meshes, right-click on actors, "Merge Actors"
  3. Select 3rd merge option (merge into ISM)
  4. Copy-Paste or Alt-Drag a duplicate

Result: Duplicate actor meshes are not visible until reloading level or building lighting
