[2019] Kuva weapon damage calculation and bugged elemental bonus

Agree. From what I can tell there are two different issues. One is that the bonus doesn't apply to splash. If you test in the sim, I expect what you will find is that the weapon does 87 * (1+0.54) = 134 damage for direct hit, and the base 187 on splash.

Issue two is that the UI is getting confused. If you look at the arsenal's numbers: 121 + 112 = 233,  minus the 47 bonus you're getting on direct impact = the base damage. Right value applied in the wrong way.

We'll get it sorted out, please excuse the construction debris.
