I developed this plugin to address a problem where survivor bots often failed to jump on "ledges" (obstacles) across many maps. This issue frustrated players because it made bots easy targets for the infected team, especially on certain maps. Additionally, the bots would frequently teleport to free themselves, which was unconventional in a PvP game mode.
