Zero morale?

[ljekio]

now - morale has dropped to zero after successfully dodging, light damage, repairs and surfacing. Before that, the team had 3-4 moral points.
The Bosun's "emergency intervention" expired just now. Does it really work so badly that it’s better not to use it? Unfortunately, I then clicked “crew maitenance” and now I have to travel for 5 days with zero morale.
