Not sure if anyone else has had this problem, or maybe I'm missing something, but...  Not infrequently, I get anomalies that reveal some broken down weapons technology that is not a module.  The options on this event are typically, "get +2 to {some} weapon stat on your ship" or "research this tech".   The latter option starts a quest to research the tech, which thus far I've never seen the option for, but I assume that's just because I don't have all the prereqs yet.  The actual bit that I'm thinking is a bug is if I take the "integrate" option, I'll gain 2 in the appropriate weapon stat, but then some number of turns later the bonus will be gone.  Also if I integrate a second weapon into my ship, I tend to lose both.  Is there some mechanic here I'm missing? (only one at a time, or a timer or some such), or is this a bug?
