Engine shuts off when grabbing?

[Gridfinned]

I have recently created a rocket based off the Falcon 9, but when I deployed my custom landing legs, the engine shut off each time a leg locked into place. I am using grabbers at the bottom and a custom hinge to deploy the landing legs. Whenever the grabbers hook on to the legs the engine turns off. I'm wondering if there is a way to turn off this setting. This is my first post, please tell me if I did anything wrong!

Some pics and a description/mod list of where the custom hinges come from would help.

Welcome to the forums gridfinned.

I do not know if there is any mod that can change the behavior for you, but I just wanted to clarify what you said.

What you saw is not exclusive the to grabbers. Any time you successfully dock to something, all your engines will shut off. Having a grabber activate is a form of docking. The game does this by default so that all the engines on the two now-docked ships don't suddenly all activate and do bad things to your orbit, or waste your fuel, or cause explosions.
