first off, you need to go into your rejuv files and replace your current rx.data with the debug rx.data that you downloaded. once youve replaced it debug should be working ingame. then you need to go to the menus, the scroll down to debug, and then find the warp to map selection. from there scroll down until you find the map you want to warp to. (tip: try only to warp into buildings, since warping anywhere outside will usually get you somewhere out of bounds)
