Falling Through The Map

[TaCTiCaLxReFLeX]

Hey, I started a playthrough of A Machine for Pigs on a youtube channel, I started recording every second I played. Now I have come towards the end of the game when I am in some sort of city and there are pigs everywhere and the city is burning and what not- There is a part where when you open a door and your 2 kids run through it when you open it. When that happens you get shoved back into a wall. Every time I go back and hit the wall, my character starts falling through the bottom of the map and just keeps falling. I was just wondering if it is just me- or is it a flaw?
