The unlimited Shields Option works fine with the reloaded crack until the end of the Mars Mission when the KI (Later the body of EDI) hit the teammate, the cutscene starts and the game crashes.
After that it crash every time enemys appear, press shift to open the weapon/forces menu, sometimes in loading screens.
That's what i found out.
Cracks is illegaly modding the game! Oh and no need to use cracks to!
