Rounding to 1 issue

We discussed this on stream, the game seems to be rounding damage by fractions, meaning you can get into situations where you shoot a target with exactly lethal damage but it lives on 1 structure because of the way the game rounded the damage behind the scenes. This is unintuitive and silly. You asked for an issue so you'd remember the issue for patches later, so here you go. Thanks for looking into it tonight man, appreciate it.

No files, tests, or entry points are named. Start by locating the damage calculation in the BattleTech mod and reproduce the reported case where exactly lethal damage leaves 1 structure; done means the rounding behavior no longer leaves the target alive in that scenario.
