its probably because of the new update where the old map is being unloaded now, so it unloads zipline and because there's no end of zipline you just continue sliding into nowhere

@@MelkayaXD i see. how it worked back then was that when a map loaded, it didn’t unload the previous map first. it would only be 10k studs away from a loaded map. if you were on a zipline before the map ended, the game remembers all the points of the zipline and your position, causing you to-after reaching the end point of the zipline-fall into the void
