I have just updated to 1.4.6 craftbukkit and only the already made elevators are working right now. I went to try and make a new one and if i set the first floor sign it will tell me theres only one floor and then i would go up and make the second one but the sign will not respond with the plugin. But i did notice if i set the second floor first it still knows where it is but the opposite sign wil not work. I do not have any errors for this.

I am building lift version 31 with the new bukkit. Let me know if there are still issues once it comes out.
