@ Vestmann...just gone and checked this myself...I've got the same problem...thinking about it there are older V4 figures I'm working on that dont have all the same morphs as the newer ones which still work OK.

That means its gotta be something I've added which installs with V4.2...can you remember/check what V4 add ons it could possibly be...one of the common features of those of mine that dont work are the Aiko morphs (though any eye related aiko morphs are fine) and the bodies of fantasy add-ons, but these aren't auto-installed with the fresh V4.2 figure, so that doesn't seem possible...

I also tried uploading the morphs onto V4.1 but this didn't work either...
