There has been a serious issue with the mouse look in this mod. I apologize for releasing it in this state and only did so because I thought the issue was something to do with my hardware.
The issue consists of the player's mouse reaching the edge of the screen whilst in-game. (not paused)
I've tried endlessly to fix this problem but have found no clear solution. If anyone knows exactly what causes this issue and a definitive way to fix it, I would be very grateful.
