I'm having this exact problem, except I'm playing on PS4. Playing as Walani, generated volcano during Monsoon (entered and left), tried to reenter via Armored Boat w/Iron Wind - carrying two thermal stones, 1 bioluminescence, and the fishbone/Packim Baggins if any of that makes a difference - on day 1 of Dry. I'm pretty sure I was on day 263 overall, but my save file now shows Volcano 1-252 and crashes at the black loading screen. On PS4, it's the dreaded CE-34878-0 error. I've confirmed my other two saves (DS vanilla, Adventure 3-14 and Adventure 3-1) both load fine, so it doesn't appear to be a problem with the base game. But I deleted the game and re-downloaded/reinstalled it anyway to see if it would help. No dice. And it doesn't look like the PS4 has any way to uninstall an add-on separately. :\ I don't know if this is the same bug that was causing PS4 volcano crashes in 2016-2018 or a new one, but I'm going to be heartbroken if I lose my only (and almost complete!) SW save Please help!
