Been noticing this recently. When I apply damage post-mortem and a teammate finishes the kill, I get no credit. Been specifically noticing it with tripmines. You can see in the video it should be more than fast enough between my tripmine damage and the kill where I should be awarded an assist. Young Ahamkara's Spine is equipped if that matters. Is this a known issue? Also, not sure if related, but when I respawn I can take damage from my own tripmines placed during a previous life. Again, Young Ahamkara's Spine is equipped, which is supposed to remove self-damage.
