How would you like the code being used? Should it be reusable or people cannot reuse it? Either way, you should make it clear in a LICENSE file or in the README so that people knows whether they should be able to reuse the code.

Also, a program is not "open source" unless it is licensed under a license approved by the Open Source Initiative.

On each and every load screen appearance, YOS would reset (if without scripts, putting player into the middle of ocean with a seashark and set player model to Michael), even if that load screen is just load online maps in the trainer.

Excepted behaviour
The mod should only reset at the first and only loading.

Actual behaviour
The mod resets even if you just choose to load online maps in a trainer.
