Bug in end game

[patmansecondo]

I found a bug at 99% of completion of the game.
When I put the 3 pieces of dress on the quilt in the past, instead of returning me in the present to face the final part, I remain in the past and if I go in Tumblety room it's totally dark and I can listen to the different music that I should have in the present. I tried everything but probably I should restart and I don't want to at this very final point. I watched the last part on Youtube and I see that it's a bug indeed.
Too bad, I feel fooled by the game, probably because it's April's fool today... :-(
