Default Negative Damage?

I did a search for "negative damage" and found nothing...I infrequently see Planetary Napalm V, in large mounts, causing negative damage to a planet--which actually restores damage points to it. I've not modded Planetary Napalm nor standard ship mounts.

Surely this has been seen before?

That would be a display glitch.
Weapon platforms with lots of shields have more hitpoints than the planet accounts for.

So if a platform has taken 5000 damage (including shields) and the planet thinks it has only 500 hitpoints (armor & components)...

When the weapon platform is destroyed, the planet will go from 5000/%bignumber% damage to 500/%bignumber% damage as the partial damage goes away and only one platform is destroyed.

The display says ok, you went from 5000 to 500, so that is -4500 damage.


In summary, it is nothing to worry about.

I'm not certain, but that sounds like an integer overrun.

If an operation would put a variable past the upper boundary for its type, it will sometimes "wrap around" past the lower bound. For example, if the allowed range is -511 to +512, and the variable has been set to 520, it will display as -503. Or something like that.

However, it seems really odd that damage amounts would be typed to such a low upper bound, so I'm probably wrong.

Edit: SJ types faster than me, and explained it better to boot.
