Hey guys. I have a door that closes an area during some triggered event. That door is a child of my collision object (or basically my walls and floor) The door was working fine until today's update. now for some reason, player and enemies can pass through the door, unless I exit and come back in to the room. Or if I reload the room. Also their not using dynamics. I'm just doing the instance_place(x, y, obj_Enemy); thing to check for collision with the parent object.
