Not sure if these counts explicitly as a typos, but the ways things are referenced in the skills menu is inconsistent. For example, Strike Commander has "+20% damage to ships of destroyer size and larger" while Wolfpack Tactics has it as "+10% damage to ships larger than frigates". Both call out the same set of ships - more damage vs. destroyers, cruisers, and capitals, but the way it's referenced doesn't match up. Same deal with Strike Commander and Missile Specialization, the former is "+50% missile, rocket, bomb, and torpedo hitpoints" while the latter is "+50% missile hitpoints" - same group of things-that-can-be-shot-down, different ways of saying it.
The way that the Ground Operations skill interacts with the actual Ground Defense rating also referenced differently, though in this case it's just wrong. The skill says "+100% effectiveness of ground defenses" which implies an additive bonus, while in fact it's a 2x multiplier to the Ground Defense rating (which is properly listed in the breakdown for Ground Defense on the colony screen). I suppose, depending on how you do your math, it's technically "correct" even as additive, but order of operations says otherwise.
Also, under the same idea of things-not-matching, the descriptions for the skills Navigation, Helmsmanship, and Carrier Group all attribute the quote to the Nachiketa Portside Interview Project (episodes 2, 3, and 4 respectively). However, Carrier Group's attribution is in quotes, ( - "Nachiketa Portside Interview Project, Ep.4" ) while Navigation and Helmsmanship's attributes are not, ( - Nachiketa Portside Interview Project, Ep.2/3 ).
