Sequencer animation stutter when using Run Dedicated Server causes character to drift. This doesn't happen when "Run Dedicated Server" is disabled.

Licensee Description:

We are having an issue with pawns staying steady on rotating moving platforms. We made the switch a while back to using a character movement controller ('Walking' movement mode) for moving pawns through the experience. While this works great for the most part, there is a slight stutter during a sequence where the characters are moved by a slightly rotating platform. The rotation is very subtle (~20 degrees of rotation over ~30 seconds), and the best I can describe the issue is it looks like a slight drift with a position correction occurring approximately 1-2 times per second. The platform movement is controlled by a level sequence

Steps to Reproduce
  1. Open the attached test project
  2. Select the Arrow Dropdown beside of Play
  3. Enable "Run Dedicated Server"
  4. PIE

Results: The characters standing on the moving platform will have a slight jitter that will cause them to slowly move on the platform

Expected: For the characters to stay in place and not slowly move around the platform (This is the behavior when "Run Dedicated Server" is disabled)
