Break formation bug?

If a ship loses all weapons, it changes type to an unarmed ship and breaks formation. Unarmed ships always break formation, no matter what.

I think that could be the explanation Fyron. However it is not a reasonable thing IMO for an unarmed ship to leave the protected formation and fly into the fire of the enemy.
