Replaced audio loading mechanism with an asynchronous one. (Not sure why I wasn’t using this in the first place.) This should fix any issues with softlocks on the loading screens.

Fixed being unable to obtain certain achievements.

If there are any issues with a loading screen softlock, please let me know how you ended up in that situation. If you need to skip past it (probably without loading music) Press F1, and then F7 to move forwards one room in the hierarchy.
