April Fool specific - no, but I've heard that there is an USS spawning randomly on the way to Hutton, very easy to miss so you have to pay attention the whole time. There is supposedly a ship cemetery of ships who didn't make the journey and scanning their data cores is supposed to bring 1Mil per scan (something about distance, perhaps?). The number of ships varies with each instance, can be 1, can be 20. Supposedly. I can't be bothered to check, have way more Cr than I can currently spend normally, but maybe it will help some newbies.
