I've made myself a carriage and I've included the attachment points as such, where I want the passengers to sit, the attachment points should read: a.standpointx and where the I want the passengers to stand, the attachment points read: a.sitpointx but for some reason I've got the problem where some passengers sit on thin air, and other passengers are standing where they should be sitting. It's a rather annoying problem and how would I go about fixing it? I know I've assembled the attachment points correctly in CMP.
