When I package my project in the 4.18 preview with nativization set to “Inclusive” I get a bunch of warnings telling me not to cook editor only things:

I noticed that all of these things are located in the tutorials folder which I’m pretty sure I’m never referencing in my project. I don’t get anything like this when I package in 4.17 so I’m led to believe this was introduced in 4.18. I also don’t get the warnings if nativization is disabled. I run into the same issue if I create a new project (using the blank template), set nativization to inclusive, then package.
