>>82186015just to recap, the bug that she encountered a few weeks ago was something that caused her base to "not be able to see the research option that begins the submarines tree" even though she fulfilled all the prereqs. (this tech eventually leads to the final sub)
that's why she reached endgame while being severely lacking in terms of her techtree, she had been playing the whole game using the starter sub.
she hex-edited her savefile to properly reveal the research, and since then she has been unlocking the required techs one by one.
