We've a 4 stage checkout process working (Select Billing, Email Address & Passwords, then Optional Shipping Stage, then Delivery/Shipping Method, then Payment Method). This all works lovely as far as getting an order through the system, with all the right data in the order details. A member account is created, with the matching password, however all of the mapped fields are nowhere to be seen.

Any ideas? Have we missed a magic tag? We are using register_member field in the checkout tag.
