i just did that glitch and started afk farming! how u say it don't work! it is just that now u might lag when u are alone so ur timing of nade throwing and jump to ledge have to change!! but the glitch still works!
it is not easy at all ! u need to release the grenade and a bit later jump depending on your lag-- more lag u need to wait a bit more longer
anyway if it don't work like it don't with me lots of times!!!
what i do is just keep running among those bots or kill them till time hits 0:00 and the fugitive bosses come out! then i kill all small bots and leave the bosses alive ( u can leave only 1 of the 4 last bosses and kill all the rest, same thing) after i am left with only the bosses/1 boss i run up near the third door making sure that the bosses still down! and then u just stand on the edge up there - no glitch or nothing!! it is just that the boss bots are "stupid" and they will not follow you up! they will just look at you from down there! now u can leave your game on for afk farm xd and i think this is much safer than doing the glitch, as the glitch might be counted as exploiting bug and stuff and might get you ban
LD ledge glitch is confirmed to be working. I just did it. You have to have good ping to do it. Press w then let go of nade. A half a second after jump.
It is almost impossible to do it without a low ping.
