No errors in emu and that teleports are linked, the video show that the users using the bug by entering the teleport and quickly click away so they can teleport everywhere they want. Maybe it's because the way the avatar enter the teleport, they don't walk to the teleport but they enter the teleport like teleporting to the teleport(door).I'm not entirely sure what you have going on there I've never seen that before. Errors? Are you sure those teleports have a link?
