All of my Celeste mods have been working perfectly up until today, when I started getting this crash when loading the game. I've changed absolutely nothing since yesterday, when everything was working completely as intended.
The error messages specifically mention the mod Monika's D-Sides, however I don't believe that the mod is to blame for the crash, seeing as though it was working just fine when I was playing it yesterday. These error messages are also why I haven't tried changing anything in my mods folder yet as I fear it may affect my D-Side save file.
Please let me know if there's a fix for this.
