What happened?

video preview
When controlling any vessel equipped with grid fins (at least grid finned first stages) using KRPC, the yaw control becomes erratic and unresponsive, causing a loss of control. In contrast, when I replace the grid fins with stock airbreaks and execute the same script, KRPC can smoothly control the rocket.
I think this problem may be related to the data that KRPC gathers from the fins.
Even more strangely, when engines are running, the grid fins seem to lose their effectiveness on KRPC's autopilot🧐.

How can someone else reproduce it?

See my repository
Open params.py and set: SKIP_BOOSTERBACK = True SKIP_REENTRY_BURN = True
Enter the game and use vesselmover to move your vessel high enough, then drop the vessel
finally python landing.py
