Updated by Anchi Cheng about 6 years ago

There is a resetComaCorrection call in exception catching for failed navigation move or bad preset assignment. At that point the probe and magnification may not be in the range that beamtilt0 is correct nor should be saved. Code is changed to skip the reset part.

In case of instrument failure at an unknown point, it would be important to check the beam tilt value before start.
