Which plugin to use to make cargo come more often?

I wonder which plugin you use to make the cargo come more often.
I would really like to change this.

It's weird.
I just started a server again today but for like 8 hours there was no cargo incoming.
Any idea why?
Even the helicopter just came for the 1st time now.
This is weird.

Do you run any plugins that manipulate in-game time? For example skip nights? Sometimes these reset the time but stay on the same day, pushing the time back constantly, so it never triggers the events.

Aaah that must be it. I have very long days. Like 3 hours or so. Thx.
