(3 of 4) How to fix Theo Parnel mission glitches... and solo the mission the slowest way possible

This video is the best part of the run and the easiest. Note: the Part 2 of 4 video shows the mission glitching out on me. This video shows how I fixed the glitch. When a mission glitches and you're blocked from completing, you basically should try everything possible to reset that part without resetting the whole mission. You want the game to reload essentally. I tried purposely D/Cing. I tried Fast Traveling to various places, I tried pressing every button I could find in the mission.

Fast Traveling to the White House and Fast Traveling back to the mission fixed the glitch.

This is my first (and probably) only clear of solo Master difficulty. This is a looooong run because 1) I'm still clueless in this mission, 2) Mission kept glitching and disconnecting me, and 3) me deciding to kill absolutely everything, and 4) me just being slow and cautious in general.

I don't recommend clearing it my way. It's exhausting. I didn't realize that the end boss could be glitched, but by the time I got there, I just didn't care. I just wanted to end the mission ASAP.

The spawns in the Theo Parnell Master difficulty Manhunt eventually end if you just kill everything instead of bother with the puzzles. This video shows gameplay without modifiers.
