Bounds generation when bIncludeComponentLocationIntoBounds is active is broken. Both the calculation of the local bounds and the world bounds are incorrect (see screenshot). When that flag is active, the bounds should extend from the root to the mesh.
We also need to fix UChaosClothComponent::CalcBounds since it uses the same flag/functionality
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-313532 in the post.
