Hey MM,
After a quick run in the latest experimental, The 'arrow passing through head hitbox' is still a very real issue.
As I mentioned earlier, its not multiplayer latency as I am in singleplayer. I felt as though it could perhaps be the hitbox not keeping up with the animation, but I did not notice any dramatic movement of the heads in my test that could make this happen.
It's not an isolated incident, as it only took a very small amount of fights to notice it happening.
Whilst I am very understanding of the fact that arrows may fly anywhere within the external limits of the crosshair lines, this is not what I am talking about. I can actually see the arrow pass directly through the head of the target, and it can happens numerous times even at very close range where the entire crosshair is completely within the boundary of their head.
In the test I just did, It happened on the biker, the guy with the hoodie on, and also the farmer. It's definitely not limited to these zeds, these are just the few that I had it happen to in my short test. I imagine if I continued to play I would probably have it happen at some time or other to most (if not all) of them. I'm happy to continue 'for science' if you feel this is required, I can also get some shadowplay recordings and slow them right down in premiere to show this.
**gotta add, LOVING A18 though**
