Converting a modular character to a static mesh can result in a crash or in an asset with corrupted data

=== Repro Project ===

1. Open the attached project
2. Select actor BP_ModularCharacter
3. Menu Bar – Actor – Convert "BP_ModularCharacter" To Static Mesh
4. Save and open the resulting static mesh
5. Note how the leg mesh of the character is correct in LOD 0 but contains garbage on other LODs.

=== Blank Project ===

1. Start with a blank project
2. Import skeletal meshes for a modular character, such as those in "Stylized Character Kit: Casual 01" ([Link Removed])
3. Set up a modular character using the "Leader Pose Component" method, as described here: ([Link Removed])
3.1. Make sure that at least one of the non-leader components contains a skeletal mesh with more than 1 LOD
4. Place the character in any level and select it
5. Menu Bar – Actor – Convert "..." To Static Mesh
6. Save and open the resulting static mesh
7. Note how mesh LODs higher than 0 and coming from non-leader components contain garbage.
