There is also something funky going on with the gate. I wasn't there long enough to see how it went wrong, but it's open position became the closed position and it wouldn't block the bots. If you closed the gate using the winch, it only goes halfway down. Opening it makes it go even higher. I don't know what could cause this except maybe the winch isn't close enough to the gate when it resets.
Also, thank you Flurry for your detailed pics and your suggestion!
