Head On Doesn't Work Against Nurse

I’ve had this happen MULTIPLE TIMES! It’s very annoying to be on the survivors end and to time it right and still get injured or downed and I’m also exhausted from a head on that didn’t work Or I could have used dead hard because I run both. I just want to clarify a bit though because I know some people will think it’s because she’s in the middle or end of a blink and she’s not, This is after the blink and fatigue and she’s walking around looking for the survivor. Another thing that needs to be fixed is the stun challenges from the rift, if you pallet stun a nurse in chase or head on her, the game never gives you credit for a stun on the nurse but you do get the points.
