The continuity I'm playing out started in July '21, and I've been just following the path already chosen. Changing the Sanctuary elf disposition would require branching off at around Day 120. I do have one internal alternate history, restarted at Day 141 because several saves made in Nov '21 have become corrupted or are somehow not compatible with v0.15. Its weird because its not every save, just most of them from that time frame. While tracking down when I bought the elves, I discovered more seemingly corrupted/marginally compatible saves, so I may wipe the Day 141 branch in favor of a Day 120 branch.
