oh interesting catch on that erasure! It should happen when you experience the rush, not when you return to the ship, that was meant as more of a reminder to upkeep but instead comes off like you mention, a double penalty, and that’s my mistake!
As for #2, yes that’s a major function of play! Using words that have different meanings is very good especially in other languages, that was a deliberate intent of the design, letting players decide what a word means in the moment they need it.
