I was driving around looking for helicoper crashes and I found one because I saw the black smoke I start to head to the crash site and the world glitch for a sec and rerenderd then poof the crash sight despawned in front of our eyes as me and a buddy where about to loot it. We searched the area for 20+ mins just to make sure we did not miss it but no crash was to be found even though we just saw it.
We where playing on a private server I have the orginal xbox 1 and my buddy has the xbox one x.
