Dead Body Glitch
No one can see you because you are apparently dead but you are glitching
You can have ramptants with it
It's not your fault but the Lag
It's been increasing since 1.15
I did it twice
Lag does not cause it. It can sometimes cause it to happen more because of lag's effects on the timing of a grenade explosion and who it effects, but the actual dead body glitch isn't directly caused by lag.
This happened to me the other day. I went 15-0 and didn't realize for a while that something was wrong. It was when their entire team spawned on me and no one was able to kill me that it clued in lol. Does this mean I actually should have died at some point but didn't? What's also strange is that match produced no cinema file for some reason so I couldn't watch what happened.
