Bukkit

What steps will reproduce the problem?
1. Fight a monster
2. Get hit, or be hit. Not sure which.
3. Check Server terminal output.

What is the expected output? What do you see instead?
No error should be recorded in the server terminal. I see this:

15:45:18 [SEVERE] Could not pass event ENTITY_DAMAGE to sRPG
java.lang.NullPointerException

-or-

15:30:46 [SEVERE] Could not pass event ENTITY_DAMAGE to sRPG

What version of the product are you using?
.6 preview build

Do you have an error log of what happened?
See above.

Please provide any additional information below.
Additional comment: The combat actually works. Both the player and monster hit and take damage. It could be anything during the combat process, the fact that it is occuring during damage is an assumption on my part based on the error description.
