Quick notes:
Matchmaking is bugged in Summit
Couldn't repair armor
Couldn't pick up armor kits - Teammates were experiencing the same issue
Some objectives were telling me to go through walls - for example; BTSU hounds that are hacked and you have to shoot the Terminals to remove the hack to kill the hounds, there's a red marker that tells you where the Terminals are when you shoot the hounds... that red marker was going through walls in an area I couldn't reach.
Matchmaking in The Summit has been bugged for a while now. So for example, say I join a group and all of them leave group because they were finishing their run, I leave group and return back to the lobby and try to join a new group, it just doesn't matchmake me into a new group, and no one ever joins my group with my group set to open. - I use to work around this by logging out and back in, usually this would fix it, but it doesn't now. There's no work around other than quitting the game completely and restarting it.
Side note that's probably super low priority, but I've noticed that the SHD brick that sits on your backpack strap on your right shoulder, it's levitating on most backpacks when I change the vanity mod.
