Check out chapter 6.8 in the NHib docs on bi-directionals. You only need the Orderline to contain the Order if you're looking to do a bi-directional. If not, then there's no need. That chapter also explains why your problem went away when you removed the Inverse() on the Order's HasMany mapping. An inverse is only required on the "HasMany" side if it's going to be a bi-directional reference.
