Wish I saved the video, but I once vaulted THROUGH one of the tiny half windows of the farm buildings on Arras (the one by F point in conquest, small tiny window next to the ammo crate).
I looked back when I realized what I just did, and honestly, it felt like that rush hour 2 scene where Jackie chan dives through the tiny coat check bars. Weird as fuck lol
Looks like the netcode cant tell where boundaries are and hard surfaces you cant pass through sometimes. Allowing you to revive through walls, jump through tiny windows, and the recent video of the guy in library on devastation jumping up through to the 2nd floor.
Game seems to try and reposition you to a legal spot when it loses you, and sometimes that happens to be going through hard surfaces.
Wish you had the video too so I could take a look, can you poke me when it happens again?
