Organic Armor: Is it broken ?

[jowe01]

It already striked me in a regular tactical combat, but it was really confirmed in the simulator: organic armor does not seem to regenerate !

Or am I getting something wrong ? In the simulator I shot once at a ship without shields and with a piece of organic armor III. The shot caused the ship to have 20 damage. The next turn I did nothing. Now, I understand the ship should have regenerated the 20 damage points in one turn (organic armor III = regenerate 30/turn), but it did not ! The damage remained not only this turn but until the end of the simulated combat. Is that a bug and if yes, is everybody experiencing this ?
