The VXI-MXI-2 interface pinout shows that a26 and a28 are ground signals. I discovered a cable with a bent pin that leads back to these two points of the card. My question is, what ill effect, if any, could occur from not having these two points connected? The station they are attached to has been operating for some time with a few quirks.
It's certainly possible that this could cause signal pins that rely on these grounds to stop functioning. Could you possibly attached the pinout you referenced? What are the 'quirks' with how the station operates?
