All the commands and everything works great, I can kill the events and trigger them when I want. But the events themselves when left to naturally spawn don't spawn when it says they will. For example, it says cargo will be out in 30 minutes but there was an active cargo.

Here is my config file:

  }
}​

The next event may not happen.
For example, if you set the cargo ship "Maximum Number On Server" to 1 and there is already a cargo ship on the server, when you trigger the cargo ship event, this event will not occur
