Activity Bot Assembly Bot Errata

Working through the Activity Bot assembly instructions, I found a discrepancy. In two places the color code for the 20K resistors is incorrect, listed as Red-Black-Brown instead of Red-BlackOrange...
===
P26 Light stays off while turning the right wheel.
The right encoder cable may be plugged into the P14 servo port backwards.
20 k resistor >(red-black-brown)< may not be making contact at either the P14 or 3.3 V socket.
The right encoder may be mounted with the sensor facing the chassis instead of facing the wheel spokes.
P27 Light stays off while turning the left wheel.
The left encoder cable may be plugged into the P15 servo port backwards.
20 k resistor >(red-black-brown)< may not be making contact at either the P15 or 3.3 V socket.
The left encoder may be mounted with the sensor facing the chassis instead of facing the wheel spokes.
P27 light instead of P26 light blinks while wheel turning the right wheel (or vice versa).
The encoder cables are swapped! Switch the encoder cables plugged into P14 and P15.
P26 or P27 light stays on while turning wheel.
Resistor connecting P14 or P15 socket to 3.3 V socket is too small. It should be 20 k-ohm (red-black-orange-gold). This resistor came in the bag with the encoder parts, not with the rest of the resistors in the kit.
