Hi. When i try to use Baby Sargent engines (As Explorer). When i call ActineNextStage, a random torque appears, a random impulsive torque. After decoupler just continue rotating by inertial. When i do the same with Space bar such random impulsive torque is not present.

I have exactly the same issue with KOS with stage.
Also i have created some automatic action group in editor like this: when "breaks" the "decouple" and then in kos activate breaks and also the same effect.
I think maybe it's not a problem of KOS or KRPC but some mod is doing something. I'm programmer.; i have donwload KRPC and Kos code and check the code and i can't find the problem. I don;t know what the game does when space bar but i guess is not the same as kos and KRPC. Maybe a problem with physic frame. Please can you give a hint to find the bug?

Thanks.

Thanks for your answer. I solved the problem using InputSimulator Library in order to simulate "space bar" key. Spacebar works perfect but stage by krpc or kos has the same behavior. An impulsive torque appears.

Greetings.

It's a list of my current folders in Gamedata. When i faced the problem i had less.
