crash when doing mine clearing with ROV

[schroedi]

When I do a mine clearing mission with a german Hameln/Frankental/Kulmbach class the game always crashes about 15min after the mine clearing vehicles of types PAP104 and Pinguin are launched. Seehund and Seafox ssem to be Ok. It is the same with US MCM Avenger when using Remus 600 ROV, I didn't test more vehicles from MCM Avenger.

Made a scenario where you can see it.
Two sides: mine side and mine clearing side, choose mine clearing side.
