I bought two bags of Wicked Good about a month and the first bag was great but the second bag was a pain in the lower unit. During two long cooks, I lost my fire four to five hours in the cooking with plenty of lump not yet burned. I have used several bags in the past and it is my favorite lump. I have changed nothing in how I set up the cooking, cleaned out the fIrebox, and all of the air holes on the sides. Has any one had this issue? Inconsistency has not been an issue in the past and just curious.
