Hi, when I start my game with Bookshelf it crashes(does not look like the potion error).
The thing is, it only crashes on my Laptop, yes I tried different java versions :).

Here the Crash:

P.S.: Sorry if it's not bookshelf causing it. I'm very bad at crash-report reading!

This is an issue with the Bookshelf API which is completely unrelated to this Bookshelf project.
