Hi guys i just installed Kerbal alarm, so i sent 3 ship, 1 to jool, 1 to moho and 1 to duna. jool and moho ship had their manœuvre done With an encounter s couple years later so i did the duna mission and i went to the space center and the exact same thing happened for both. I clicked on "fly" engineer was showing null values and all i could see was stars, the nav Ball was also showing stars from the back ground. I clicked on space center in the escape menu and stars was all over the space center too si i had to close the gane and when i went back to the gane that ship was Gone.... Repeat the story for the next vessel.
Sorry for my english i hope you understand. I could make a video of you want to see. I use planet Shine, kis, kas and engineer redux and Kerbal alarm.
