done another test this morning, changin the name of the others DD of the convoys; I also tried to save quite far from the zone.. near ostende and zeebrugge (always at least 50km from them), this time when the game loaded I had like a mine coillision.... water entereing from everywhere and ppl dieing almost instantly. The death screen said it was a collision... Uh I was on surface. Watching with the mission editor the campaign scr I noticed in that zone starts the huge minefield around the eastern coast of uk. Anyhow it's getting annoying.
