Same here before the update I was getting 1 FS every 2 ore 4 days ( I do around 75-90 boxes per day, since the update , only spirit ore, soulstone and cry, did they nerf that? I thought I was just unlucky.
Also 1 spirit ore per box ?, less then usles I use around 7 000 - 10 000 only spirit ore, per day, at least make the boxes drop around 1000.
