Fixes and small quality of life improvements!

This patch introduces some fixes and improvements over Lux-EA-B1!
Visually, little changes with this update, but this is a more stable version than Lux-EA-B1 and serves as preparation for work on Lux-EA-B2.

Thanks to @soup6020 for pointing out the redistribution of irrelevant OS files ( #3 ) and @Lolothepro for pointing out a bug ( #2 ) earlier than anyone else.
Both of those Issues have been resolved.
