At the moment I’m adding AdMob, which I also have some problems with, but I think it’s worth dealing with this problem first.

Console

I’ve been trying to add various packages to an empty Unity project for a while now, and every time I add them to the project, I get the same errors in the console. They don’t seem to affect anything, but I’m afraid that if I skip them, they will snowball in the middle of the development process.

Here is what is displayed in the console.

Instance of GridPaintingState couldn’t be created. The the script class needs to derive from ScriptableObject.
