DD self-destroy in multiplayer mode

[lynx]

Hello, I Have a problem with DD in multiplayer and 100% realist mode, the problem is the DD self-destroy and don't I know reason, can somebody help me?. It is maybe cause of the mod IRAI (IRAI_0_0_39_TheDarkWraith and Update), when I play with this mod disabled they don't self-destroy, but DD is inoffensive. When I make the missions I put DD in Elite, can this be?
thank you.
