High Jump?

[Black Beard the Pillaging]

well (dont try this if your not desperate or you may have to reinstall the game)

You could go to the game folder and delete most recent patch file but this will most likley mess up the game ( this was just a theory thats never been tested)

[Ninja Pirate]

If you do that the launcher will just update it again to most current version.

I do miss my super human jumping skills though
