Dear Vdr, how many things I've lost in these years!
I found your Campaign workaround to continue game, sorry for my ignorance.
I've also read in TwoS documentation that's not a good idea make harbour raids :
"Due to several engine and AI limitations, harbor raids in SH games are generally very unrealistic and they are commonly regarded as a cheap
way to "pump up" your tonnage. Also players presence within 60 Km of traffic generator nodes (mostly located in harbors) will prevent game
engine to spawn any convoys or units which can lead to potential campaign corruption"
I just can thank u and anybody else who made this Megamod ( I imagine how many nights spent on pc to mod and test game...)

However, when I have anything to ask , I 'll write here.
Ciao
