The jetpack frame with harness rings and the jetpack hooks files were replaced due to a faulty measurement (from my side) of the jetpack's lower edge which helped me to approximate the jetpack frame size. All the values were reduced with 3%, not too much on small pieces, but significant on larger parts. I also replaced the collar and cod stud attachment file, but in this case I added 1 or 2 more measurements that were missing. Sorry for any involuntary misleading.
