Hello. When creating a new file of type ScriptableObject, the file does not see the script to which it refers. I can customize the file, however in the project, I also cannot find the script to edit it. What could be the problem?
Some info about Missing script warnings, GUIDs, renaming GUIDs, etc:
EVERYTHING in Unity is connected to the above GUID. It is super-easy to inadvertently change it by renaming outside of Unity. Don’t do that. Instead:
close Visual Studio (important!)
rename the file(s) in Unity
in Unity do Assets → Open C# Project to reopen Visual Studio
now rename the actual classes, and MAKE SURE THE FILE NAMES DO NOT CHANGE!
If you are NOT using source control while you do this, renaming files is an EXTREMELY dangerous process. Use source control at all times so that you can trivially revert if you miss a critical step and damage your project.
