Hello all and thank you for visiting! I've just started to play KSP in the last week or so and I've really just begun to enjoy the game! However, with the way I like to design my crafts, I'm having some trouble doing so through either a bug or just lacking knowledge as what to do. So, let me start by explaining my problem! Lately, I've been trying to use a decoupler or adapter underneath Liquid Fuel Engines to attach booster rockets or to have more stages. Unfortunately, when this happens, the Engine will prove absolutely 0 thrust, even though it looks as if the engine is operating as it should. Am I missing something here? I've been looking for the last day or so and only finally decided to make a thread. Any help is much appreciated! Thank you!!
