Misplaced decimal place on Celestial Death Ray hull damage!?

Not a bug. The different races are more adept with certain turret types. Trolgars are the best with projectiles, Celestials are the best with Energy turrets. So if the random generator throws a death ray to a Celestial then yeah, that is going to hurt.

That doesn't happen always though, and it is very rare to happen in the first galaxy if you face them there. But it can happen.
