I have yet to get to play a ground mission in the builds released so far. Is there something special you have to do? No aliens ships are ever spotted on the ground. No matter how long I follow one in the air (until my fuel requires me to return to base) they never land. When I intercept there's only 2 outcomes:
1) I destroy the ship outright.
2) The intercept screen appears overlaid on top of the world map and about 10 seconds later the game crashes.
So how do you actually test the ground combat?
