That's odd. I just downloaded the file I uploaded (to make sure I had uploaded the correct one last night 
) and cleared my gerber directory to make sure no old files in there, then loaded Raspberry Pi Zero_fixed.fzpz and created gerbers. They look fine in my local copy of gerbv. I zipped the directory of gerbers and renamed it to fzpz (so it isn't a real part just unzip it) and uploaded them. I'm on Win7 although that shouldn't make a difference. This part has been so strange its possible there is yet another problem still here though. The pcb file is the one from the pi 3 which of course may have problems too. I'll poke at it more, there are a few more things that should be corrected before submitting a correction for core (I am going to try and figure out how it breaks pcb anyway, just because I want to know, I think that may be a fritzing bug).
