What happened?

I'm trying to mess with contracts using KRPC.

My script looks like this:

#include <iostream>
#include <krpc.hpp>
#include <krpc/services/space_center.hpp>

int main()
{
    krpc::Client conn = krpc::connect("Launch into orbit");
    Vehicle v(conn);
    krpc::services::SpaceCenter space_center(&conn);
    auto cm = space_center.contract_manager();
}

When I run this while I'm at space center view, the program crashed with 0xc0000409.

How can someone else reproduce it?

Create a career game.
Start playing it.
Run the script above.

What is your environment?

C++ krpc client 0.5.4

KSP 1.12.5.3190 w/ making history and breaking ground

Anything else we need to know?

No response

It turns out that I need to enter Flight scenario for this to work correctly.

Reopening to remind me to document this and/or add a check.
