I was shooting a velonasaur from atop the proto-ark's northern metallic thing while prone, I shot a couple times then suddenly got sent to respawn screen. This is the first time this ever happened to me so I was confused.
Server was extinction 449, I noticed that my shots were having trouble hitting even though I looked like I had line of sight so I kept getting closer, I figured my shots might have been hitting the ground, there might be some wierd collision there and I might have slipped in while standing on it, that could have been what caused it. But from my perspective I was on top of it as shown on the second image, except I wasn't mounted because I was using a longneck.
