OK, but one question.
When there's some THP damage which is not, let's say, "mirrored" by LHP damage (for example, when an already banged-up limb at negative uninjured LHP is it once again), when such damage is healed?
Like, for a plausible example, we have someone with a 3 LHP arm, who gets hit a few times in that arm: first for 2, then twice for 3 - which would bring it to 1, then -2 and then -3, but there would be still 2 more points of damage toward the THP. Even when the arm would be healed completely, there would be those 2 missing points.
