[2021] [Bug/Glitch]Cannot Complete Pentagon Mission on Hard Difficulty

After defeating the quad copter and final wave of NPC's, the instruction is to leave the mission area and return to DARPA. Proceed to the elevator and the mission ends while you are in a loading screen during the elevator sequence. You do not get credit for completion and don't get rewards. Please look into this as it is a progression blocker for the Black Tusk Operations project.
