Upon grabbing all of Delta's stuff, it continues to tell me "Leaving Mission Area" even though it say's in my Journal under Lost Armory that I need to "Return to Delta."
It won't let me interact with Delta even if I ignore the "Leaving Mission Area" and go to her. She just has the yellow marker above her but no interaction button.
If I restart the game, or leave and restart the save it just resets me to before I've collected Delta's stuff.
(Another side bug, but during the mission I pulled out the big sledge hammer which I got ages ago from the Bloody Ties arena doing a glitch, when I was using it to kill zombies during the "Collect Delta's Stuff." part... for some weird reason it just turned into the Scorpio and the Sledge Hammer had totally vanished from my Inventory. (I haven't even started/finished the challenges to get it from the Pilgrim Outpost, I was also never given it by anyone. (It shows up as a crossbow in my inventory, and also doesn't shoot.))) I don't think this is mission related but it happened to me during the mission anyway.
