We verified this by putting our sensors right over the black tape during the practice day -- sure enough, it was triggering them!

Our autonomous worked fine on the practice field (which did not have the black tape), and fine at home, but would not work on the field itself.
Just another heads-up that that black tape is certainly an issue when programming for branching. I have attached a screen grab from the Chesapeake Regional Webcast which shows the black tape at the Y.
