I went to the ruins where my Aporkalypse Calendar is located to reset it. When I look at the map the room says it is empty. When I go inside the Calendar is there but the buttons don't do anything but lock the door. I try to save/quit and reload but when I do the game crashes. It says the mods might have to do something about the game crashing so I disable them. When I try to load the game without the mods it still crashes. I reported the bug with the save slot info. Thanks!
I have no idea.
