Engine crashes when creating static mesh from skeletal mesh

Issue: Engine crashes when attempting to create a static mesh from a skeletal mesh using active LOD > 0.

steps to reproduce:

  1. open the skeletal mesh editor using an asset with multiple LOD’s.
  2. set minimum LOD = 1 (or above)
  3. open the animation editor that uses the preview mesh from what’s open in the skeletal mesh editor
  4. select ‘make static mesh’ from the menu at the top
  5. observe crash behavior

i’m guessing this is an array mismatch between verts at LOD 0 and verts displayed as LOD 1 in animation editor, but just a guess. this occurred during natural editor use when converting hi poly assets to lo poly assets for use on mobile. by default i set a bunch of skeletal meshes to use LOD 1. I then needed certain poses saved as static meshes from the animation editor after which the crash occurred. originally detected in 4.23, but tested in 4.24 on a clean project (using FPS template) to verify if it was an asset issue or engine issue .
