Description

When a unit deals damage through AmbientDamage=, be it through railguns, particles, or sonic beams, the unit's modifiers do not get applied to the damage.

For example, if a Titan picks up a firepower crate, its damage gets doubled, but if your railgun-equipped Mammoth Mk. II picks up a firepower crate, it does nothing.

The same bug applies to the FIREPOWER veterancy bonus, as well as the house's Firepower= multiplier.
