For some bizarre reason, they removed the autosave function that POE 1 had, so if the game crashes, you lose everything you did that day. I guess to make the game harder? It seems like a really bad decision that just leads to frustration.
I just wish that doing poorly in naval combat would still result in a boarding fight, just maybe at a disadvantage. Giving out a TPK is too harsh, especially on hardcore, it feels like your run was stolen from you.
