So my current run is getting towards the endgame, but apparently the final battle is "teh broken" right now (V18), and this was fixed in the more recent experimental (I guess?).
Can anyone (Sathra has much experience here, I know), give me a quick rundown on what needs to be changed to get the last research available? I've got all other researches completed, including Battleship techs. I believe the vital, missing tech is Alien Leader Interrogation.
A related question is how the availability of research is checked by the game -- If I were to mod leader interrogation to be based on an already-completed tech (such as officer interrogation, imitating the official fix), would that enable me to research leader interrogation in my savegame? Would I need to capture another alien leader to do so? I've already captured two or so.
