Brentai reset the server because of a clone issue. Seems like all the chunks weren't saved, so a lot of work was lost. More recent work is sporadically scattered. He was afraid of saving everything due to fear of saving the ghost, sadly. Anyways I got a lot redone, such as grand centeral station being UNDER the cafe instead of replacing it and the line to the Zeppelin.
Here is the DEALIE with hellish nightmare dimension. You can only travel SO FAR ( tried brakes, speed had nothing to do with it) by minecart before the game gets confused. As such, there is a stop hub in the glass underwater tunnel. YOU MUST GET OUT AND GET BACK IN BEFORE HITTING THE BUTTON. If not, you will crash into nightmare hell dimension and possibly leave a ghost. IF THIS HAPPEBNS TO YOU, DO NOT QUIT RIGHT AWAY. Teleport somewhere. I'm not sure of all the warp points but /warp zeppelin and /warp ledzeppelin will work. Wait a minute or too and then quit. The ghost may still exist, but underground and off the tracks. COnsidering what happened when Brent reset the server, if a ghost does pop on the tracks we'll just have to deal with it, if Kicking doesn't work.
So if you make ANY LONG TRIP, split it with the mechanism I used in the tunnel. If you need help implementing this, just ask and I will do so. And again, YOU MUST GET OUT OF THE CART.
Worst case I'll just design the mechanism so you HAVE to get out to use it.
edit: decided not to leave anything to chance. Hopefully the mechanism is intuitive to use.
