Quoted from killerrobots:So I poked around at the boards and connectors looking for loose wires but didn't see anything but when I put it back down everything was working fine. Seems like I have a loose connection somewhere. I am sure it will happen again eventually and maybe I can pin down what is loose.
Still have no idea how to troubleshoot a Spike 2 system but it is working for now.
Fairly common issue with this game and spike2. About once or twice a year you have to reseat connections on those node boards below the inserts.
