Same happened for me. Was thinking it was me and new computer. Even deleted program and reloaded. So shaking my head, along with you, as this is a bit frustrating. lol
I had this today , all the melon loader mods don’t work if you use the new delivery organiser , the old version still works but yeah use the old version and all still works
I was just going to add a few mods and I noticed that it looks like there are a lot less available and the one that I found a lovely explanation of how to install it on STEAM, I tried to install it and some folders were missing and others were empty. This was my first attempt ever with a mod so I'm definitely confused. lol I'm just going to play the game normally. Although lately it has been freezing and shutting down on me quite often which is annoying but I am hoping that stops.
i have a comprehensive video i just dropped on how to install mods from scratch. Maybe that can help? you can always reach out to me too if you need help.
All my mods stopped working and completely broke my game to the point where everything was gone including the register. I had to start a new game after removing the mods.
Mine did too until I asked the creator of this video for suggestions and he said to delete all mods that are furniture mods, like freezers, shelf, pallets, etc and it worked.
