This is less a tool and more a reminder of how to revert the movement and linedef code to the older version to allow linedef / trigger skips (as the code was updated after the initial release to prevent casual players from accidentally skipping linedefs and causing softlocks and other map issues).

• Open the console (` is the default key for me) and type the following without quotes: "p_fixlineskips: 0"

This setting is saved to your system file for the game and does not need to be reentered unless you do a full uninstall and reinstall.
