This is not a bug, at least not a bug in the firmware. LulzBot wired up the v3 with the two extruders backwards and relied on a firmware hack to cover for the mistake. This was an ugly workaround and a far better solution is to simply cross the wires when plugging in the toolhead. So in drunken-octopus, T0 is the same extruder that is used for the single toolheads. This means that for the v3, you need to cross the wires if you want it to match up with the labels on the toolhead itself.

By chance you know what wire I have to cross?

@keawepoo: Yeah, when you plug in the toolhead just swap the two molex connectors the go into the toolhead.
