My game is sometimes crashing around the time when infantry eject from the helicopter above the water, though it is possible that I've done something somewhere else in my mission to do it.
I've only been testing it in the editor so I don't know if that is a factor as well.
Crashing only started on the latest Dev Build 0.55.103.960 (17/04/2013)
Including the mission file as well {F18935}
