Hi, This is FRC team 3197. GRIP crashes when we connect the switch output with anything else. When we connect inputs to the switch with no output, it works fine, but when we connect the switch output it crashes on startup. Do you know how to fix this? Thank you, Ethan J.

Maybe the output is getting connected before the input? That would make sense.
