one bug i noticed on my Tron LE is the Zen Flasher
when you go down the lane not going into arcade it flashes until the drops are hit (feature) but i notice it flashes even during bonus counts when field is dark for your feature count downs and in other areas where it gets "double flash" where it flashes for something else but still pulses for ZEN (not feature / bug)
anyone else notice this not sure if its a LE feature or not
