So I am making a project using the mod patchouli, which allows the modder to quickly make a guidebook with json script. I made a test bool and it didn't show up in game. I tried again and it still did not show up. This time I opened the assets folder while I run the client, and it seems like mcreator overwrites the assets folder every time, deleting extra folders/files. So I locked base mod files, but the same thing still happened. I kindly request Pylo to add a option to lock mod assets folder or even better, not overwrite it at all.
Thank you for reading my long block of text. I hope you will consider my suggestion.
