[Issue] Infantry Taking Damage While In A Building Despite No LOS To The Level With The Infantry

[furyn22]

Brief Description *

MegaMek v0.50.02

I have infantry in the ground floor of a lvl7 building. Princess cannot see the ground floor because of an intervening lvl 5 building. Princess shoots the top floors of the building, trying to collapse the building and this is incorrectly transferring damage to my infantry. Looking at Total Warfare p 172, infantry shouldn't take damage if the attacker does not have LOS to the building hex and level with the infantry.

Total Warfare p.172 says:

Because infantry are comparatively small and are trained to
use even the least bit of concealing terrain to their advantage,
units outside a building hex cannot fire directly at infantry units
inside a building. They must fire at the building hex instead. As
with other units, the attacker must have a valid line of sight to
the building hex, as well as the level within the building occupied
by the target infantry unit. Damage applied to the building hex
from an attacker that did not have LOS to the level occupied by
the infantry has no effect on the infantry unit and only damages
the hex’s CF.

3. Steps to Reproduce

1. Put an infantry unit in the ground floor of a tall building (say 4 levels tall).
2. Position an enemy unit so that they can see the top level of the building but not the ground level. (put a lvl 2 building in the way).
3. Using the enemy unit, attack the building (collapse).
4. The ground floor infantry will take damage despite their being no valid line of sight.
