In Lego Harry Potter Years 1-4 PC, there is a glitch that in Hogwarts when trying to enter the Slytherin Common Room using a slytherin character, Not the Dungeon that you can enter with Parseltongue, I can open the door to the common room using a slytherin character but once I do that and the door opens, there is like an invisible wall that prevents me from entering, I’ve tried all slytherin characters I have( which is every single one besides voldemort) but nothing works, I've completed story mode, Hogwarts crests 100%, True Wizard 100%, Student in Peril 49/50 (The last one I need is in the slytherin common room), Red Bricks 19/20 (Last one is in Slytherin Common Room),Gold Bricks 196/200 (The last ones I need are the one in slytherin common room, the one obtained after getting all Students in Peril (which I can't get because it’s in the common room.), The one obtained after getting the last red brick (Which I can't get because it’s in the common room) And the one obtained by just finding it in the common room. I've finished everything else in the game EXCEPT THIS ROOM. I've encountered GLITCH after GLITCH after GLITCH in The PC version of Harry Potter Years 1-4. All I have had to search all over the internet to solve and all have been solved but I haven't found a solution to this problem. Please help.
