An opponent has an inbound gift of a sub containing only an Inspector. The gift is from another opponent who was eliminated after the gift was sent. Before it gets there, it momentarily crosses a small spot not covered by my sonar. Sometimes, while I'm trying various combinations of launches on that outpost - which means running the time forward and back, the gift stops making it across the dead spot. So, not noticing at first, I set up a schedule that would win the outpost, only to come back later to check and find I lose the outpost.
Since I no longer have time to make up the difference, I'm a bit cross.
