---------------------------------------------------
What steps will reproduce the problem?
---------------------------------------------------
1. When the plugin is loaded and is working, I try to do the command /prophunt
2. The Server then ends with a "Internal Server Error" and kicks me from the server, but the server is still up and running.
3. If I try /ph, nothing appears in the console and nothing appears in chat.

---------------------------------------------------
What is the expected output? What do you see instead?
---------------------------------------------------
= I was expecting to see a list of commands or some response from the plugin, but instead I get this in the console and that "Internal Server Error" on my client. Here is the console message:

---------------------------------------------------
What version of the PropHunt are you using (/version Prophunt)?
---------------------------------------------------
= 1.42 and I also used the latest version but yet I still get the same error.

---------------------------------------------------
Do you have an error log of what happened? (If yes, pastebin that error log)
---------------------------------------------------
= http://pastebin.com/pbjG997U

---------------------------------------------------
Please provide a clean Startup log and your config file.
---------------------------------------------------
= My config has not ever been edited I just got the plugin and wanted to setup an arena but it wont let me because of this error.
http://pastebin.com/mDYkt9HJ is my startup log as well as the error.

---------------------------------------------------
Please provide any additional information below
---------------------------------------------------
= I also have the plugin "BlockHunt" installed because if PropHunt didnt work, I would switch to that. I even disabled it with Plugman soPropHunt was the only Hide and Seek plugin running. I currently have the latest version of "LibsDisguises" as well as the latest "ProtocolLib".
