The distance point. Sorry, I think it was the 100. I first succeeded in a mission in the large asteroids, then accepted one mission at the point. While that was active, I accepted a second one.
When the first came due, I couldn’t collect. When the second came due, I couldn’t collect it either.
Does the game allow you to sell items required for missions? If so, that is the likely cause. It prevents sell all, but I had cargo of the same type, so I sold individual amounts.
The Nav points are still on the map after fail, is this as designed?
