I found another TIR bug. I hit F10 in the tower offline and appeared to move forward about 4-6 inches while getting the "head position saved" message for each button press/movement. I hit it several times and it kept moving me forward until it started moving me backwards. I repeated this cycle a few times and it didn't seem to always reverse direction in the same spot. I hit F10 with the TIR LEDs off, program still running, and nothing happened except the "head position saved" message. I turned the LEDs on again and F10 moved me forward and back again. I reset my default head position, with TIR LEDS of,f to default with HOME and F10 and still had the same behavior when hitting F10 repeatedly.
