Bug Battle - Rel 1.51

Hello,

I had a bug in the battle where my ship (X.E.S. Corvette-1) was destroyed without appropriate damage.

That's the battle log. Only one attack with 5 damage (1 absorbed some mitigated). Ship had full Hitpoints 18/18.

But why ist the ship destroyed? Do I get something wrong?

Here's the link to the save:

The Battle happens directly after finishing the current turn.
