Earlier tonight there were 2-3 times in a single match on alpine where I shot a mech under a kilometer away, hit them, saw a shower of sparks but the reticle did not glow and no damage was apparently registered. They were moving in the middle of an open field not hiding near a building so I know it wasn't environmental effects of sparks flying.
Yesterday I was on canyons in a spider and while jumpjetting I clipped into some terrain and took a bit of damage to my leg but launched up in the air.
These might not seem connected but to me they suggest that host state rewind is doing linear interpolation of motion based on a single point (most recent speed on server side?) which would explain how the clipping/bouncing motion would launch a mech up and how we are still having hit detection issues.
I could be way off, but the theory matches the symptoms.
