[N_Danger]

KSP Win 32 ver 1.05

Problem: When switching ships in the tracking station the UI get corrupted and the ship goes missing when the game is restarted. 

Mods:

Reproduction steps. Got to tracking station at space center

                                 Switch between 2 ships in solar orbit going to Duna.

                                 After the second or third switch the Nav Ball and altitude indicator on the selected ship are blank and MecJeb readouts show NaN. 

                                Returning to the space center there is just a star field, no buildings

                                After restarting game the ship is missing and the crew is shown as missing at the space center.
