Yeah, I have tried already. No one responded to the previous person who had the same issue. It is an old save, but I really can't be bothered to 100% the game again. I also don't want to start again and spend the time getting to Vesunna to have it still not work.No idea. Are you trying a new save of a old one? Because this game doesn't like old saves.
Also Try search the thread, maybe someon already got a solution to it.
The main problem is that Vesunna causes the game to crash when she's in my party so it appears the patch didn't work properly. I have redownloaded it and tried again just to check.
