Headshot percentage chance still shows as 1% although headshot protection is turned off

Hi, thanks for implementing the contract scaling for building health!

Just found what seems to be a cosmetic bug: when going for a headshot with a maxed pilot and a mech with the Mara mod, the screen displays the hit chance as 1%. This is after I disabled headshot protection in the mod.json file. I was still able to make the shots like normal, so it appears to be only related to the display.


Relevant part of mod.json:

```
"CalledShot": {
"DisableAllLocations": false,
"DisableHeadshots": false,
"EnableTacticsModifier": false,
"BaseModifier": -1,
"PilotTags": {

}
}
````

Start with the CalledShot settings in mod.json and reproduce a headshot using a maxed pilot and a mech with the Mara mod, with headshot protection disabled. Compare the displayed 1% chance with the shot's actual result; done means the displayed chance reflects the enabled protection setting while normal shots remain unaffected.
