1. Fixed a bug concerning the Tutorial Complete achievement preventing users from unlocking it. (If it doesn't unlock automatically you may want to wait to complete the game so you can start a new one. This achievement should be unlocked after you complete all the tutorials, the last being the one on sprinting after you unlock and enter through the front gate of Painscreek.)
2. (This update was released earlier but wasn't significant enough to have it's own patch note post.) Re-added the invert mouse option, as after the Controller Update the invert axis function in the Calibration settings only worked for controllers and not the mouse.
