, by design; if it cannot find the script you are wanting, then it loads the default which prints out all of the information seen.
You can find that script in "Asset Library/Scripts/Default.lua".
Yes you are right, it should display an error rather than printing all that information though, but at least it didn't crash hehe...
Tip to all users: When adding a script, you need to add the .lua extension onto the name. In the latest version(0.8.0) of skyline, you do not need to specify a path to the script as it should exist within the resource list.
