I played some hours and i found two minor things, i think can be solved easily. There is a bug that u dont get boarded ships if u destroy them it worked only once for me. Additionally i noticed if i had an ideling new fregat, however they are called, and a enemy ship came to the planet it didnt auto attack instead it floght along with him 
P.S.: I think the addon has great potency, because it has what i like BIGGER ships and the titan class is awesome
P.S.S.I m looking forward to some mods (im a big stargate fan)
