I was very pleased to see the ship upgrade bug was fixed in the change log for 2b so I decided to play a game and try out some of the Yor weapon techs. I had researched several weapon and defence systems an wanted to toughen up my Defender class ships so I went to the shipyard, clicked Defender-> Upgrade-> Weapons and saw my extensive list of upgraded weapons. The warmonger in me giggled like a school girl and clicked the beam weapons subtab... Nothing! Missiles tab... Nothing! Massdriver tab... Everything! The same happened in defenses and modules tabs, all upgrades are filed together under one tab and no longer sort properly.
