So I just went to check the pin centers on my pin headers and couldn't figure out what was going on until I realized that the male 1x20 pin header \(HDR\-M\-F\.254\_1x20\) and female 1x20 pin header \(HDR\-F\-2\.54\_1x20\)h ave different center points\.\.\.
Female:

What kind of maniac would offset the center of the part so when you flip it it offsets 1 pin?
