When playing a mission last night where I was required to deploy my ghost to two amplifiers I was unable to deploy my ghost at the second amplifier. You can see in the attached video that the "Deploy Ghost" prompt comes up and I hold down X to do so and it simply goes away without deploying the ghost. It comes back up again and I try again but it doesn't work. I was able to restart the mission and it worked fine so it only happened once. Figured I'd share for the dev team!
