Scavenger arty's number of shells also depend on the amount of muni left in your store after you use the ability. For example, vs AI I use it when I have 700+ muni and it just barrage non stop until the HQ is down. Usually, as OKW you'll rarely float muni that much. If you have ~200 muni, the barrage is just like the Ost 105mm arty strike.
I know that, but no. Genuinely bugged.
Drop flares, barrage, barrage stops.
Minutes later, flares magic out of nowhere, barrage happens again.
Repeat every few minutes until I manually drop one- it then starts repeating on that spot.
