Description

Instanced Static Mesh components update incorrectly in Standalone and Packaged game. When hit, all of the instanced static mesh components will snap to a singular location instead of each individual instanced SM be translated back a few units.

This is a regression:
Working in 4.16.3-3561208
Not working in 4.17.0-3573198

User Description:

every collision of instances react all at once. If touch one, all the other instances react.

There is no problem in '4.16.3' There is no problem in '4.17 PIE'.

'4.17 Packaged version(Dev,Shipping)' always has problems.

Steps to Reproduce
  1. Open the attached test project
  2. Play in Standalone game
  3. Fly the player forward and hit one of the boxes

Results: All of the instanced static mesh components will snap to a singular location

Expected: For only the box that was hit to be translated back several units. Each box hit would do the same. (This is the behavior in 4.16)
