Trying to stand on an object with physics enabled using the default third person template causes some very weird behavior. The object and character will jitter wildly and launch either one far away. This happens at any size and weight. Disabling character mesh collision completely and messing with movement component settings helps some.

Steps to Reproduce
  1. Create a project with the third-person template
  2. Place a cube in the level and simulate physics on that cube
  3. Jump on top of the cube

Results: Both the character and the box are unstable. They will jitter and clip through each other as well as the ground until either one is launched off.

Expected: Player character can stand on object.
