The problem is that Cassord did a half-ass job with fixing the pixel_x and pixel_y problem.
The trigger SHOULD be something similar to:
"cty" = (/obj/effect/step_trigger/teleporter/random{affect_ghosts = 1; name = "escapeshuttle_leave"; teleport_x = 25; teleport_x_offset = 245; teleport_y = 25; teleport_y_offset = 245; teleport_z = 6; teleport_z_offset = 6},/turf/space/transit/north/shuttlespace_ns15,/area)
This is a snippet from Bay's map. The problem is laziness. Cassord replaced every instance of step with pixel when he SHOULD have replaced every instance of step_x and step_y with pixel_x and pixel_y. But he just replaced all the words 'step' with 'pixel' which lead to this.
"aIZ" = (/obj/effect/pixel_trigger/teleporter/random{affect_ghosts = 1; name = "escapeshuttle_leave"; teleport_x = 25; teleport_x_offset = 245; teleport_y = 25; teleport_y_offset = 245; teleport_z = 6; teleport_z_offset = 6},/turf/space/transit/north/shuttlespace_ns1,/area)
Notice how it says /obj/effect/pixel_trigger instead of /obj/effect/step_trigger? Welcome to breaking everything.
