Wont let me up the stairs for breaking in achievement. I talked to Huang, told him I didnt want to go, then went down the left set of stairs and snuck past the funeral. Then I tried walking up the stairs and I keep getting interrupted by the stupid funeral cutscene, and the stairs wont let me up. It's like an invisible wall is blocking me from walking up the stairs. Then the funeral ends.

I keep quitting out and re-starting from the menu, and I have the choice between going to the funeral or sneaking past and it ends the same every time I sneak past. It just wont let me up the stairs.
