Description

Physics object bounces around erratically when interacting with moving/rotating object. In the test project you will see multiple instances; some will not behavior erratically but many will. The licensee says that sub-stepping needs to be enable to see this behavior but during testing, it seems to happen regardless if Sub-stepping is enabled/disabled.

Steps to Reproduce
  1. Open the attached test project
  2. PIE

Results: As the square rotates, the physics object inside will bounce around and behave erratically

Expected: For a physics object of this size to behave as closely to real world as possible and slide around the inside of the square as it rotates
