Ghost Game instance

So I have a game instance that is in the project that im working on that i deleted about 4 months ago, when i go into the file folder the game instance is there, but when i delete the game instance from the past which was connected to almost all of my old files it screws everything up. this file doesn’t exist yet everything is working. Ive created many blueprints that are running fine, am i going to have to redo all my bps because of this?

After Fixing the issue with this ghost game instance i now have the issue where everything is no longer reading that it works
