Hey,
I was looking on the wiki (https://www.galciv.wikia.com/wiki/Missile) today and noticed that the missile technologies go all the way up to "Blackhole Eruptor", where as mine stop at "Nightmare Torpedo", which is just after Photon Torps.
Wondering where these extra techs are? I'm playing on "Ultimate Edition", is that not the most current version of the game?
