NPCs were teleporting next to me during the search for black tusks portions. Was happening more than once.
Drones from golds were spawning three back to back. Not sure if this was intentional on the number and near 100% accuracy but damage should be reduced a bit with the frequency of the drones. (BTW, I was doing the mission solo.)
Golds were bullet sponges with the default survivalist loadout. Felt extremely weak. Even a super 90 purple shotgun at point blank range took 4 shots to kill a normal non elite NPC.
Stats appear to not matter except for the gear score level. Had better stat weapons drop and they were just a bit less in gear score. Even though the damage was shown as higher on inventory, the effectiveness of such weapons get completely trumped by a weapon with weaker stats but higher gear score.
The survivalist crossbow just felt like a glorified explosive grenade and the signature round rarely dropped.
Search for black tusks in the parking garage especially buggy. If you retreat into the hallway leading to the area and kill the secondary npcs there, they respawn. You can do this over and over again. Happened to me 10 times in a row in one mission. Gold elite during this encounter did get behind me a couple of times. Once it ran through the doorway in the far back right that connects to the other part of the map. Another time it just teleported behind me in the hallway leading to the fight and just mowed me down.
Drones and NPCs suddenly become speed demons. To explain, an NPC or drone about six or seven car lengths away in game can run up to you before you can even switch weapons. You can be dead if you were loading a slow weapon like the shotgun from empty.
Sudden large amounts of damage from full armor to requiring medical assistance come out of nowhere. When there are gold sniper types or a few snipers I can understand this insane damage. But to get this in one shot with no snipers in the room and no indication where it came from at all? Happened multiple times and seemed like maybe the NPC was able to shoot through a column?
Lag during boss fights. Every so often things appear to speed up for a second and a half. NPCs teleport short distances, sounds lag behind and things are just out of sync for two blinks of an eye. Not sure if this is just because of the beta server. (BTW my XBOX One is hard wired to the internet not on wifi.)
