Bukkit

What steps will reproduce the problem?
1. place sign on subdivision
2. type [RE] on 1st line and price on second
3. press done.

What is the expected output? What do you see instead?

The very first time I did this it worked, and it leased correctly. Now it is giving me this:

What version of the product are you using?
1.4.1

Do you have an error log of what happened?

The only Log I could find was the Console output pasted above.

Please provide any additional information below.

Hi! I did some more testing and it seems that it only happens when trying to place the lease sign on an admin claim, if you do it on a personal claim it works just fine.
