Jump Height Stuck/Doesn't Change

For jump height to be enhanced, you need to have SKSE installed. Make sure you have it enabled in my MCM too.

Use the "Reset Better Vampires" menu option.

Jump height will not be enabled whenever you start the game up on your computer. Game settings must be reset each time, they don't stay in saves - this is just how the game is set up.

The good news is, I've set up my mod so if you wait 1 hr (game time) your jump height bonus will be applied and last throughout your current gaming session.
