Update Instance Transform Rotation for HISM isn't working in a packaged game

Using 'Update Instance Transform' to rotate HISM instances will work in PIE, but won't work in a packaged game. This is a regression from 4.19.2 (CL-4033788).

This issue was reported and tested in 4.20.2 (CL-4302132). This has been reproduced in Main 4.21 (CL-4305553)

1. Download and open the attached project
2. Play in Editor and notice how the Hierarchical Instanced Static Mesh instances are rotating
3. Package the project for Win 64 Development
4. Launch the packaged project

Results: Instances don't rotate in packaged game.

Expected: Instances rotate in packaged game.
