Game crashes

[adas]

Firstly, a big thank you to the developers for this really awesome game.


So after trying out the latest version, here's some stuff that doesn't work for me:

a) The replace aircraft with another aircraft option causes the game to crash
b) Overwriting a saved game causes a crash
c) Lastly, my game has kind of frozen at a particular point in time. I attach the bug report.

Apologies if I am not posting the bug report in the correct format.

Code:
