Yes, we testers noticed this a bit in earlier beta, but have not been able to reliably reproduce it. There are a couple of theories on what the cause is though.
- Are you having trouble hitting stationary players or moving ones?
- Which part of the body is it that seems to be resisting your bullets?
- Are your targets proned or in cover at the time?
- Do you notice any contortion in the enemy model, like the arms pointing the wrong way etc?
