SpringArm causes physics to fail for a character standing on the physics object

User Description:

I am updating my marketplace content for 4.11 using preview 7 build (EDIT: RECHECKED WITH PREVIEW 8, STILL A PROBLEM).

As part of said update I noticed that the ability to stand on moving PhysX enabled vehicles was lost. It worked fine in 4.10. I could spawn on moving vehicle and walk around on it. In 4.11 the character stays in place while the vehicle moves (even clips through collision).

After hours of pulling my hair out I noticed that the bug went away after I removed SpringArm from the vehicle.

I know this sounds bizarre so I created a demo project for you to replicate the bug.

Steps to Reproduce

1. Download and open the test project (BugSpringArm411P7.zip) from [Link Removed]
2. PIE
3. Stand on the dark platform and shoot towards the corner
4. Stand on the light platform and shoot towards the corner

Results: The light platform (without SpringArm) will carry the player along. The dark platform (with SpringArm) will not carry the player.

Expected: For a physics BP that contains a SpringArm to carry the player along like in previous engine versions
