Part Design pocket won't open holes

Problem description

Since Part Design can't handle multiple bodies, I decided to work around it by making a partial pocket, filling in struts that would connect parts into one body, and then shaving off the bottom to open up the holes. But when I try to do that, I get a totally non-specific error about "Cut out of base feature failed."

To see what I'm talking about, go into Pocket003 and change the thickness from 0.199 to 0.2.

The models seems poorly constructed I get errors when trying to refine the model. Please consult the forum for help requests. If there still seems to be a bug come back to this one.
