Killed C87 on my DuetWIFI, how bad is it?

Due to unfortunate slippage of a screw driver, I broke it in half. Looks like it's just some sort of shunt for the Z axis driver, can I live without it, or should I attempt to solder a new one in?
C87 is connected between one of the Z motor outputs and ground. Its purpose is to help protect the Z driver if the motor is disconnected when under load, and to reduce EMI. Revisions 1.0 and 1.01 of the Duet WiFi didn't have those capacitors.
If you want to replace it, it is a 1nF X5R or X7R 0603 ceramic capacitor rated 50V or greater.
