Nest of Vipers instant fail


#1

I got to the part of the game where you have to go to pribyslavitz when i get there the NPCs are bugged in both camps, the cumans and the bandits are all huddled inside the middle tent in their own camps, when i try reloading it tells me that i have failed the main quest. Does anyone know a fix for this bug? could it be because i unlocked the cartographer perk early on and gotten the fast travel to that location unlocked?
