Tracking healing for multiple level 2 wounds

A character acquires a level 2 wound in a mission (on their arm, say).

Immediately following the mission they get one healing tick on that wound.

Next mission they acquire another level 2 wound, to their leg.

The question arises here: when acquiring the second level 2 wound should the level 2 healing ticks (currently 1/2) stay as is (option A), or get reset to 0/2 (option B).

Assume for the sake of the question that at the end of this mission the PC will again receive one tick of healing.

If option A: after the mission when they receive one tick of healing both the older arm wound and the fresh leg wound will be fully healed - the leg wound will be gone after only a single healing tick.

If option B: after the mission when they receive one tick of healing they’ll still have both the leg and arm wounds, even though the arm wound now has received two ticks of healing.

Is either correct? It seems like the only fictionally appropriate method is to track both level 2 wounds separately…

Also a related question: wound penalties are applied when fictionally justified. If a PC had two level 2 wounds, and both applied to a situation would they receive a total of -1d penalty, or -2d?

Option A. Filling all the ticks on a row remove all injuries on that row. It’s an abstract system, so adjust the fiction accordingly.

Don’t track ticks per injury: legionnaires would get stuck out of action for longer, putting more pressure on those currently unhurt, and players would have to track yet another thing. The game is already hard enough.
