Game breaking bug

[spoiler Alert]

 

Hello

I met a very specific game breaking bug after the alien abduction part.

I finish this part and wake up in my bed bud it's impossible to go down the stairs of the house. If i try a fix view of the down stairs occured (like if you focus on the door behind the stairs in the zero level of the house. ) and i am stuck. It's like the stairs are stucks someway and if you try to force it you just bug the game.

 

Well, i try everithing : change equipement, recharge multiple time the save, recharge save during alien abduction and redo the part (useless), try to do everything upstairs but nothing work.

 

If someone have some idea...

 

Thanks !

I finally find the problem : it is link to one option in the user.ini : the vsync. This is very strange. Without vsync all is OK except the ability to down stairs in my house, the only solution is to reactivate vsync on my config...
