I encountered a BIG glitch/bug. I was on day 29 for story and wanted to try endless. No instructions on it and I left without making any potions and when I went back to story mode I went ALL the way back to day 1.
More an oversight than a bug. Nothing was deleted; it just resets the default to day 1 after you play endless. You can jump back to day 29 via the pause menu.
