Bukkit

What steps will reproduce the problem?
1.Running the server with S86 Powers installed on 1.7.2
2.
3.

What is the expected output? What do you see instead?
Nothing wrong is happening (other than some powers not working which I expected) It just spams my console with the error message below and I'd like to either hide that message or get rid of it entirely.

What version of the product are you using?
S86Powers v4.3.6

Do you have an error log of what happened?
Error]: [S86 Powers] Packet41MobEffect not found!
(spams this multiple times a second.
Please provide any additional information below.
I know that this mod is not currently update for 1.7.2 but some of the stuff still works so we like to use it on my server, but I was just wondering if you knew a way to stop this error from popping up and spamming my console like 20 times a second.
Thanks a ton, Great Mod!
