Well the thing is this, After i finish my homework in the drowned nations and i get to the place called TOMB where is in the middle of the floor the same tatto that is in nameless ones back and you walk on it a Thunder spell falls and kill you, and where nameless one tells to the party that he have to go there alone,
when i want to go to the Portal avoinding the tattoo a bug appears, the game just get freeze and nothing happens , no portal, no nothing, i tried every patch but it was a failure can somebody help me out?
OHH ONE MORE THING I CAN HEAR the wind and i can close the game with alt tab and cliking on it on the taskbar and clicking in close soo is really strange. i cant attach the image but do you remember when you start the game and nameless one is resting and morte get close to you for your first dialogue, where you cant do nothing but wait morte to get near you and start talking well here happens the same , the only thing is that it just get stuck.
