I've noticed something I've never encountered before, this:

It would seem that when my boat is even slightly damaged it starts smoking and won't stop until the next patrol

.
Even worse is when i'm underwater, the smoke still rises above the surface

.
Then to make a bad situation worse, it starts burning now and then, then will go out only to start later for no reason
Has anyone else seen this?
I think the only modding I did before finding this was to upgrade Commander from v2 to v2.2. Is it a commander related problem or should I just reinstall the game?
(or maybe they've just given me a steam-powered sub :hmm: )
