I keep going to the Checkpoint right before going over the bridge for Harcourt. Guard won't put up the stop sign so the drone can investigate the jeep. I keep trying to resume & load saved games to no avail. I can't complete these missions with these bugs. Can I force that guard to put up the stop sign? If I go through this checkpoint, I will surely be shot dead. I've only gotten this to work once. Got shot trying to get close to the ship to off some soldiers. I have to either resume the game or load a saved game. I'm too far along to start this scenario over again.

This goes step-in-step with the other bug preventing me from seeing tasks in the diary or lines that move on the map. This scenario seems buggy.
