Imported FBXs that use UBX will import their collision rotation incorrectly. You can see this when scaling the collision non-uniformly.
Found in 4.20 CL# 4369336, 4.21 CL# 4541578, and 4.22 CL# 4618663
The collision will scale on the incorrect axis. If you look in the StaticMesh Editor the rotation is set incorrectly
The collision would scale correctly
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-67153 in the post.
