The issue seems to persist.
I can try going back through the entire game making the same choices, but that'll taking longer than loading the save already at the grove.
I ran through on a new game from tutorial to the grove (Dialogue skip made that easy, tysm) and when I talk to Jester to confirm that I'm done messing around it starts to fade to white before resetting back to before that conversation. This time I even forgot to swap out the potion (I'm realizing now).
