List sorting for loft gone wrong :(

i have a list of square surfaces floating around in mid air - all rotated slightly (pink)
and i would like to loft each corresponding edge.
it works on most of the squares. but on 4 it has the flip wrong. does someone know what i did wrong? or now what to do to fix this issue?

help is very much appriciated :smiley:

Not at my computer right now, but try flipping your second list of curves, using the first list as a guide, before lofting.
