My game doesn't stop to crash

Hello,

I need a strong help. My game always crashes in these conditions :
- i exit a single mission while my submarine is on the surface (no crash if i'm submerged)
- some explosions occure (torpedoes, bombs, fuel explosions)

This is the error message i get : "The Instruction at 0x####### referenced memory at 0x#######. The memory could not be 'read'"
