Found a stupid three way switch and I'm mad that it works.
Working in a knob and tube home trying to figure out why in the hell one three way switch had five wires on it. Had to diagram it out to figure out what the hell was going on but I finally worked it out. So, it works, but has the stupid side effect of changing the polarity at the light depending on the switch positions.
Honestly I'm impressed they fucked it up so hard that they actually got it "working." Don't worry I ripped it all out and rewired it properly.
