Hi, I am having a problem with FMRS in KSP 1.6. I am using a falcon 9 style rocket. After booster separation, I go to land my first stage, but as I get close to the ground I am losing the ability to throttle (up, down, full, 0, etc) the engines. I know that FMRS is the cause as everything works perfectly without FMRS active. I believe it may be something with the second stage hitting the ground first as I've observed that I've lost control of the throttle around then. Am I doing something incorrectly?
