Were you killing a non-existent copter?  Can you give some more detail about what you were doing when this fired?

Don't know... just saw it appear in console... asking players what they have done to reproduce this error.

How can I kill a non-existent copter? So I can test ?

Steps I tried to reproduce the error
Spawned my mini - destroyed it with rocket - no result
destroyed random copters with rockets - no result
tried /gmini after copter destroyed - no result
I cannot reproduce the error as of right now !

Perhaps /nomini ?

nah tried that too after destroying it ... nothing popped up 

Changed Status from Pending to Closed

I also have tried to recreate this issue. I've watched as 4 players did everything to their Copters from my rcon. And nothing happened! I even removed CrazyCopter to see if that was conflicting with yours. I still get this. Even when there are NO Players on the server.

 I am sorry but I feel I must remove this and find another Plugin that offers something similar. But thanks anyways for trying!

If the data file contains only the word null, then that was an error that crept in from the previous version.  If that is the case then delete the file manually.  Otherwise I do not understand why this is happening.
