The thread you linked explains how seeded growth work on lunatic, which I understand. The only new thing I learned from it was that apparently you can reset seeds on a units join chapter, which doesn't seem to work for me? Whatever I had managed to do with my save file in the past caused every branch of fate reload to not only reseed each unit, but to count them as new units which didn't overlap each others log book entries. Ordinarily trying to buy a character from the einherjar shop that you already bought from a branch of fate would overwrite the previous entry unless you started from a new game. So to get two Corrins from a single system in the log book you would need to get to chapter 12, buy Corrin, then restart the whole game from new game as opposed to the branch. I somehow could get every branch reload to make the game think I had restarted the game, and every unit would count as a new entry in the log book, and get new stat growths. I'm not sure if it was a glitch that was patched out or if there is something that needs to be done to get the branch to reset every seed, so I was wondering if anyone had something similar happen to them?
