Bukkit

What steps will reproduce the problem?
1. Create a new gate on 1.6.4, maybe hook it up to a daylight sensor (I have gates with and without but I can't tell if the one's with are causing the issue)
2. Wait.
3. Check the server log.

What is the expected output? What do you see instead?
I expect there to *not* be exceptions every few seconds.

What version of the product are you using?
0.2.1

Do you have an error log of what happened?
Yes: http://pastebin.com/bWB1MYB3

Please provide any additional information below.
Using GatesPlus with daylight sensors to simulate "open during day, closed at night" behavior. The server pops these exceptions every few seconds when a new gate is created. On reset it doesn't seem to, but the server will occasionally crash with "ConcurrentModificationException".

use the comand /relode in the server normaly it would bee fixt if not let me know
