Grenades despawn after death?

A bunch of my friends and I have been trying to figure out why when we throw a grenade before dying, it doesn’t blow up. It seems like it just despawns. We are so used to other Halo games just throwing a final grenade for a “From the grave” revenge kill, and it just doesn’t seem to be happening if we throw the grenade within 2 seconds of dying. What is going on here, 343? Is it the animation, or do grenades just despawn when you die?

I’ve noticed this too I’ve potentially missed so many from the grave kills because I’ll throw a grenade and it will just despawn its frustrating as hell


Same goes for the desperate final melee strike that should result in a double beat down but instead only you die. Seems like a sync issue lie with the aim assist?

I’ve noticed a lot in fiesta when we both hammer, 90% of the time, I will die, and they live, even when it seems like we swung at the exact same time. Lower ping wins I guess, idk.
