I know abou the roof. I've checked the bushed as well as one of the Family Guy posters were in the bushed, never found one in the kitchen, dining area or the room with the sofa where you find I think the hammer, room next to the garage

Idk about that Family Guy poster thing, but as for the "missing posters" I believe I figured that out. The Hayley one just had the visual element ticked to OFF, infact the code is still listenening for a pickup so if you knew exactly where to stand and look you could still collect it. Obviously the visual element makes this way harder than it could be expected to figure out but it should be set right in the V.1.0.7 going up right now.
Watching the stream now, at about the halfway point you actually had the Haley poster on screen for like a frame in the big bush by the shed, might not have been a bug afterall but I'll keep an eye on it. Also a suggestion for a speed run category could be fastest getting Klaus into the pool, or alternatively how quickly you can drown Roger ha
