I dont know if its a bug or if this is normal, hopefully someone can tell me.
I had a medium hulled ship, with very basic weapons, like a few mass driver III's or something, but over the course of it surviving a LOT of battles, it had 113 HP and a lot of experience. So, as my weapons got better and miniturization improved I had a new model and upgraded the old one. It lost all its HP and experience, is that normal? Now it is as though I just built it off the assembly line, which is sorta lame.
