When I load in 1.0.10 it does not show Cargo Ship will spawn after x minutes when reloading config.  If i move back to 1.0.9 it does show Cargo Ship.

"Restart Timer On Entity Kill": true,// Because you enabled it. 

In the old version. If you enable it, it will notify you twice of the next run time.
In version 1.0.10, I modified it to notify the next run time when the cargo ship is destroyed. only once

What I meant was when reloading the plugin it does not show CargoShip in the rcon console time of the next cargoship.  

Here is an example 
Imgur: The magic of the Internet

On 1.0.9 it would show new cargoship event time just like every other event on the rcon console when reloading plugin or server starts.

On 1.0.9 it will show twice, the first time is inaccurate.
"Restart Timer On Entity Kill": false,//If you disable it, the time of the next run will be displayed immediately
