I know how Nems power works for its hit box which may explain the clunk, but I'm not entirely sure it hit even taking that into account.

It's the clunk and no Survivor hit sound effect that is making me think your right, but with hit validation and stuff I am struggling to answer confidently.
Hard to know anymore what counts as a hit and what doesn't.
