I forgot a critical one :  The magnets.

All native Poser figures come with magnets, and most figures have around 40 symmetrical magnet errors. Some small, some huge.

The magnets, their zones, the dependencies are not the same left-right.

With all those magnet errors in place, the figures are simply unusable.

Not a big issue for me, as the very first thing I do with all Poser native figures is : DELETE the MAGNETS.
