Is there some way to modify the files on the OM Darkwaters mod to stop duds? I turned them off in the gameplay settings after I started a campaign, but I still get duds. Found a fat juicy convoy, biggest I ever saw, gotta be 16 merchants and three escorts in the west approaches. Frustrated. Yeah I guess it's cheating but I want to sink some ships rather than have duds and prematures.
Are the gameplay settings locked in once you start a campaign?
