I think I know what happened to yours Paul. In test fitting I noticed that if I just glued the wing half's together as is the fuselage would be too tight for the opening for it between the upper wing halves so I when I glued them I moved them outward taking up as much play in the alignment tabs as there was. It made the bulges of the landing gear fairings not line up perfectly, and a slight step in the joint at the wingtip, but nothing a bit of CA filler and careful filing didn't solve. The end result was a near perfect fit at the wing roots.
