While playing Solonauts I ran into a problem where contradictory timelines for my IDs caused confusion. That is, I could restore the timeline of one character but in order to send the other home I had to change the timeline to something else. There was a paradox (in the logical sense) because the timeline could never stay in a state that ensure the home conditions of both. How does one handle this problem? Should I assume a multiverse in Solonauts?
You are supposed to send them home one at a time, not all at once. Set the timeline for Character A, then invert it for Character B, and so on.
