The code to extract the FBodyInstance from the overlapping component is incorrectly interpreting the Overlap.BodyIndex as a BoneIndex. This results in incorrect bodies getting the force applied, as well as log spam.
Fix is proposed in the UDN thread and looks reasonable.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-21811 in the post.
