I'm getting oddly paranoid, because I'm having absolutely no issues with wear and tear, and am starting to wonder why. o_o Heck, my Viper would sit in the sun with the heat at 110 to 130 percent for five solid minutes, get shot at LOTS, jump all over the place, get shot s'more, bounced around the interior of a stardock like a ping pong ball by accident, was fine, and this was during long stretches of not suffering any battle damage. I briefly had a Cobra, don't remember any wear and tear there, and I've legit crashed my Type 6 freighter so hard it took out two shield bars, along with overheating every time I jump, and no damage. The only time my ships have gotten damaged outside combat was Interdictions, and since I stopped doing those (decided that, when Bounty Hunting, I was better off just lurking in resource fields) I've only, very rarely, had to pay a literal 1 credit repair cost, regardless of the ship type.
Hopefully my good fortune holds! I don't even want to guess what my freighter's repair bill would be. T_T
