hatch causes model not to load

[amankd]

ive set up my airlock exactly as described in the wiki tutorial but it refuses to load, it loads without it but as soon as i add the airlock ccollider the part stops loading in game without so much as an eror message, what am i doing wrong?

What type of collider are you using for the airlock? it sounds like you are trying to use a convex mesh collider on an empty game object, only use capsule or box colliders for hatches, especially if just starting out
