see above curves (and their CV’s) - (nearly) all are arcs below 90 degree.
only the last arc is a bit more then 90 degree 90.0001 and is represented by a “2-span-arc”
seams like loft has some problems with this setup.
see overshooting surface-part at (x)
I would expect this surface.
@Gijs can you repeat this ? thanks for assigning to the correct person.
