Camera Orthographic FOV below a certain level affects transforms and rotations of items in scene.

I’m trying to fake a orthographic camera to avoid lighting shadow issues that seem to exist when cameras are set to orthographic same way your example content is doing

creating a isometric camera object in 4.3.1 and ran into a strange issue setting the FOV below 5 screws up the transform and rotation of the instance in the scene outliner and prevents the transform from being changed setting the fov to 5 or above fixes the transform lock out but you have manually correct all the transforms and rotations to affected items in the scene.

Object is a Actor or Pawn based blueprint with a camera component with FOV set below 5 scene instances cannot be positioned and get random set of values applied
