THe problem with the new 'stargazers' trait and other new equivalent traits

[Captainbeastfeast (Rat-ee-JiK)]

is that you can't re-equip your civilian ships with the engine type that you want, so you have to make new ships instead and have to disband the old ones if they aren't what you want. Also, you can't choose whether your troop transport ships have hyperdrive or jump drives. This is problematic and limits the usefulness of the trait, although the 10% habitation boost is quite nice.

It's a long wait, but I noticed after I got Jump Drives my old subspace drives were retroactively equipped with the Jump Drives and started acting like normal ships again.
