Okay so here is my problem i cant kill kayran because when i get on his tentacle near the end of the fight nothing happens no matter how much i spam my left mouse button i have seen a similar topic here where someone uploaded a save after kayran was dead i tried using the link he provided but the files were already gone so if someone could please take my saves and beat the boss for me and than upload ,i know it's too much to ask but i dont really have any other choice since i already tried almost all the solutions (Lowered my resolution/graphic,etc) posted here about that bug and nothing seems to work so anyways here is my save.
