Question on crafting and Skill Archaeologist

[Kazeto]

Just making sure, you are aware of the fact that there can be more than one page in crafting and once you have enough recipes you have to switch pages to get to some of them, right? Because unless it's some sort of unique case, you should be able to craft any item that you disassembled and got the effect for.

And Archaeologist is a passive ability; it removes some of the wrong answers when you get to the guessing stage of artefact identification (I believe it's one wrong answer removed per rank, but I never really cared that much so I'm not sure); that might or might not make it easier depending on your luck, since even after removing some answers you might be left with things that you never checked for which would still make it a guessing game.

No idea about the officer question since I generally have a team with one of every sort of officer before finding any on away missions and thus I never bother to try changing them.
