Hello !
I made a geostationary orbit in ksp with 3 satellite around kerbin, It was working well until I leave my save and come back on it :
The 3 satellites wasn't separated by 120 degree as before but the 1st one was like 20° from the 2nd and the 2nd was 35° away from the 3rd and last one..
I did not changed the gravity in debug panel or anything like that so I don't know why is this happening...
