In this house, the player has to disarm quite a few traps, but he also needs to activate a portal upstairs.
When I used the crystal (the one used to activate the portal in the cellar) on the portal, the game crashed, I have tried quite a few times, and each time with the same result.
If this is the only way to activate the portal, then we can all feel fu***d until a fix comes out. Or maybe its a crash due to a misuse of an item (in which case, how the hell do i solve that hosues riddle? 2hours of this screenshake is making me regret BF4)
