I've noticed a few items in the game which seem somewhat out of scale, but since I've been doing trap doors this one is really noticeable;

Agnete the Pickled on a castle tower trap door with the anvil lighthouse ladder behind her - those are okay, but looking for a rectangular rather than round one all I can find are the square monsters like the one next to her. That's used in several cave dungeons, I never really paid attention before since I always play in first person perspective, but in 3rd person they look really weird and oversized. What I'm wondering is the CSTrapDoor01 really big enough to be used as a freight elevator or did I download some kind of mesh mod that screwed this one up?

Sometimes they make models bigger then "realistic" for one reason or another. You can easily scale them to your liking, up to 10x as big. IIRC if you hold S and click + drag
