Kerbal Space Program

Seconds after I circularize my orbit at Mun to 20km it starts changing itself without reason like there was windstorm randomly pushing my spacecraft around causing big changes in the orbit on the opposite side (in prograde and/or retrograde directions).

Operating system: Windows 10 pro, version 1511. Os built 10586.494
Processor: Intel i5-4570 @3.2GHz
System type 64bit
Graphic card: NVIDIA GeForce GTX 650 Ti

If you want more info on the hardware I can look after.

My game version 1.1.3.1289 (x64) (steam)

The game was just freshly installed.
After installed the game I also installed the following mods:

betterburntime
bettercrewassignment
camera focus changer
easy vessel switch
indicatorlights
Kerbal Attachment system
Kerbal Engineer Redux
Kerbal Inventory System
Module Manager
Precise manouver

Then when I noticed the bug at Mun, so I uninstalled all these mods. And built a new craft (except I left out that little "motherboard" that comes with the Kerbal Engineer Redux mod, and I had that on my old ship. I rebuilt the same ship with stock parts. I went to moon and this is what happened.

Also see my older report (when I used mods) #10087.

If there is any other information I can give just ask.
