Bug Description:

  1. RM works well on Static Mesh Actors placed in a level, whether as startup map or loaded on the fly.
  2. RM works well on user created BPs when it is added to the BP TEMPLATE itself.
  3. RM added to BP INSTANCES placed in a level only works when the level is played as an entry map.

Steps to Reproduce:

  1. Create two maps A & B.
  2. Create a Blueprint with visible components, and place one instance in each map.
  3. Add a Rotating Movement Component to each instance.
  4. Place a command in map A to open map B.
  5. Run from map A and fire the open level command.

Result:
Only the BP instance in map A rotates.

This problem is still present in 4.27. Although it seems to work fine in PIE, it plays up in Standalone or packaged build. In fact, it not only stops rotating, but will then begin rotating on a different axis even though that axis (z) has a Zero value.
For me though, it doesn’t matter if the level is loaded straight in or loaded in sometime after begin play.
