Is it a bug or a wad that wrecks are seen from everywhere as soon as you enter a system? Seems not very realistic to me and too much of an indicator that something happened here.
Also, should they not deprecate after some years, at least for the non precursors one? I know it is not realistic perhaps, but on the other hand I guess that having wrecks stay eternally will in the end ruin the entire database with thousands of records, no?
