Removing the permanent flood penalties ?

[Akka]

Hello, I have a little problem with my game.
It seems that, once a province has got a flood disaster, the penalties associated with this disaster (no watchtower or fort being able to be built, movement of units severely reduced) never goes away, even long after the flood is gone.

So okay, I modded flood out of the game. But I still have a problem : how can I remove the effect from provinces who took a flood in the past ? Is there a console command for that ?

Thanks in advance.
