On Halo 4 in the mission Reclaimer, once Palmer tells you to grab a jetpack the blue markers showing you where the jetpacks are located appear roughly 1000 meters away from the mammoth. I didn’t notice this happen in the flight however.
Make sure and file a bug report about in the Halo Support site if this is something you can reproduce https://aka.ms/HaloSupport
Thanks for the reply. I’ve reported it on the support site but I’ve seen some big halo youtubers point this out as well as a few other minor bugs so they are definitely known about now.
