I am unable to even begin the Lincoln memorial mission because the computer that controls the entry door is broken. I cannot interact with it.
Doing the mission solo on Hard level, and have already killed any hostiles I can find within a 200-400m radius.
I didn't get a video, but I did get past it.
I was solo'ing on Hard level when I couldn't get in. I experienced this two days in succession. So I decided to step up to Challenging and use match-make just in case. As soon as I re-crossed the zone boundary where the floating options screen is, new mobs spawned inside the Memorial building, visible from the steps outside. From then on it was as expected - so I'd been wasting my time exterminating everything in a 400m radius. xD
Killed the last mob and was immediately able to interact with the laptop computer connected to the gate lock. Previously I wasn't receiving a prompt to interact, along with the square controller button icon.
The match-made players never arrived though lol
