Updated Graphics issue when going to spots

Okay lets say I walk against the rock mountain on Truth and Reconsiliation, you notice that you have a barrier blocking you. Its because they dont have the updated graphics aligned with the original layer’s close whatsoever. Also my freind showed me a spot above the ‘Halo’ Level that is above the map on a moutain and when walking up there, I have to watch where i step because I will fall through as 343 thought making it have more land area up there was a good thing, but truth is if you get up there you fall through as part of that area wasnt in the original so I have to watch where I step. 343i should have thought of these issues.
