Im offered a 30% Bonus for completing War Thunder Tasks (which i did) and I got a 10% Bonus Rune in my Welcome-Box. Do they stack? And will the Bonus apply if I finished my Task during the "Offer-time" but hasn't been accepted yet (waiting for the approval but since ist Sunday it seems to take some time...) Anybody experience with this?
