I realise I shouldn't have done this and it's fair if I can't receive much support but I figured I might as well just ask. I ended up wasting part of the day on an activity I didn't mean to do. I hadn't saved in a bit, and so I decided to try using the calendar feature of the mod menu to essentially reset the day by warping to the start of it (I believe the day in specific was October 4th). After doing so, the calendar screen that shows up between days seemed to have stopped showing.
The screen shows up on other saves so I'm pretty sure it was my messing with the calendar that did it. Is there a way to get it back or am I just stuck without it? If its the latter then that's fine, it's my own fault admittedly.
