I'm having the same problem as Proply. Whenever I launch, I'm not charged nearly enough. I was charged under $1000 for an $18000 ship. Testing it on a Stayputnik drone attached to a cheap SRB charged me a little over $200 (should have been over $3000). I thought at first it might be a problem with one of the other mods I have installed, Construction Time, but I uninstalled it and I'm still not getting charged nearly enough. Okay, so I messed around with it a little, and it's only a problem with HardCore mode. In normal mode, it charges the correct amount, but when HardCore is turned on, it only charges between 10-15% of the stated value of the ship.
