Yeah, I think this true, but I don’t like it. Then again I haven’t been using strike fleets for anything but sudden strikes. I sent one ship off against what I thought was a transport and instead found that it had bitten off waaay more than it could chew.
I don’t know about bugs, but this reminds me of another “why”: when I did stick a new gun or even just put a missile into an existing hardpoint, the game prompted me to save it as a new design. For missiles this is dumb, but anyway you can give them new names, however whenever I went to repair that ship it would pop up two cards, both identical, which I assumed were the two “versions” of the ship but it was impossible to distinguish between them because they had no names or any other identifying info.
