I was playing Far Cry 3 and was about to begin the "Kick the Hornets Nest" mission when I died 3 times (Because I suck). Suddenly, when I returned to the area with a hang glider and it didn't spawn. There was also no missions on the map and no NPCs in the nearby town. I restarted from the last checkpoint, restarted my system and killed myself ingame but nothing worked. Any help?
