I need some help figuring out what just happened. I will explain my problem in really tiny text to avoid spoilers. This involves a sidequest that occurs at about 10% completion, it becomes available around the 10th official mission (the ones where it recommends a rocket launcher)
I was just on the part where you extract Emmerich from the base camp, when Sehantropolopodop appears in that cutscene. I call D-Horse and start to run, the helicopter guy says he can't land until I "lose" this giant Metal Gear. So I keep running away from the base camp when I accidentally leave the mission area. The screen blacks out, and when it comes back in Emmerich is gone and so is the Metal Gear, seemingly. I fly back to Mother Base and there's no cutscene or anything, I'm just here. Did I break the game? Is something supposed to happen now? I feel like we just witnessed the unveiling of a bipedal Metal Gear and there's no cutscene with Ocelot or anything? And where is Emmerich then?
Also, when I look at the side op in the side ops list it appears to be already completed.
Edit: I figured out what happened. I left the mission area so apparently it just ended the mission for me and I have to redo it. This game is loving stupid sometimes.
