Silent Cartographer Glitch not working?

i know that it works in the original and CEA edition but has anyone been able to do this in the MCC edition. we tried and it feels like there are bumpers add so you can’t do this yet i thought they left all glitches intact.b Can anyone confirmed they messed with the campaign. http://www.youtube.com/watch?v=Jrv1IRCHJKw

Well idk if it matters but i believe the Halo CEA is running off the PC version and not the Xbox so that might have something to do with it? not sure but when i get to this level i’ll give it a try and let you know

thanks ya let me kno cuz none of the glitches in the game at all i tried are working but this one we were at it for about an hour
