If so its from the repository. I don't have anything except a plug test part in Fritzing at the moment, so no local stuff (and I had never heard of this part before). Maybe you guys aren't getting updates from github? My core parts shows a date stamp of 09/11/2016 for all the Camdenboss parts so perhaps you guys are missing an update (which should be automatic, mine was I'm sure)? Buzzer-v15.fzp just before it shows 06/10/2016 as the date stamp so this must have been the November parts commit. (edit:) See if you have
4001_4_x_2_input_NOR_gate_multipart.fzp
as this is one of the parts that arrived with the November updates.
