Fallout Shoulder Weight Problem

[Minoumimi]

Hey i am having so much problems weighting my shoulders since a few days...

i never had this problem before.. 

i think it is the  Uppertwistarm  that always gets removed when i export

if not what part should i need to weight to fix this

i tried every possible clavicle weighting and it won't fix it

 

**Edit** Siiigh Nevermind hah!

yep blender had deleted my upperarmtwist bones...

i am still having problems with that dam clavicle but i guess only more practice will help me on that
