the ship will change its orbit a little bit by itself, a mistake or not?

[mgsrr]

help guys please! I can't understand-is this a game error or not? . after launching the rocket into the ring orbit of Kerbin (and not only), the ship without warp and with the engine not working itself changes its orbit by 1 meter in 3-5 seconds. the heavier the ship, the faster the orbit changes. I deleted and reinstalled the game, updated the version- the effect did not disappear. there is a mod between the 2 and the manager module, the game version 1.12.5. 3190

The change you’re seeing is actually very small- 0.0002km is 20cm. Even tiny variations in the vessel’s attitude will change the orbital parameters slightly.

thank you for answering- the ship is stationary, gyrodines are turned off, there is no rotation. the orbit at the same time has a constant increase in value/

I believe this is a math error possibly due to the drivers Visual C++ and Net Framework... maybe  my version Visual C++ 2013-is 12.0.30501 and Visual C++ 2015\19- is 14.28.29334.

Net Framework 4.7.1.
