I have a multi body part with an extruded cut through all solids. Each solid is derived out to its own part. I edited the extrude feature in the multi body part and removed one solid from the selection set. The cut was correctly deleted from the solid, but when I open the part its still there. The only way to make it update correctly is to manually edit the derive feaure in the part. Caught it just before it went off for cutting. 2012 SP2, all hotfixes, win7 64 bit.
Reproducible on R2012, but it does work fine on R2013 now. Maybe you could have a try on R2013.
Sorry for the inconvenience! Maybe I was lost in this multi body derive workflow yesterday, and today I find it also reproducible on R2013, and maybe there are some additioal steps I made yesterday. It is so curious!
One issue has been logged against R2012 as 1470436 in our database.
