First, let me reiterate that DA rocks... obviously I love it, or I wouldn't find bugs all the time.
Been getting weirdness in the Ship Design screen: often the tooltip popup that pops up when I scroll over the icon for a system installed on my ship, it gives different stats than the list of available systems on the left (which are, AFAIK, correct). Once I even managed to SAVE a ship that had systems that didn't ass up. It was a cargo hull with three Warp IIs and five life supports or something like that. It never had the benefits of the systems that were in excess of its hull space, but I couldn't figure out which ones were "fake," and I had to remove them all.
Unfortunately, I am pretty sure I erased that particular design. Idiot!
NOTE: this does NOT appear to allow violation of the rules, it is just confusing.
