Was obtaining "coke" intended to be left out from patch notes? How to obtain?

Did you contribute at all during prep phase? Did the Hamlet reach lvl 2?

when i checked they were 51k during battle phase and i didnt hand anything in during the prep phase but i had won a few defenses. i dont think those helped the price tho. maybe like i said, the better you do in the previous cycle the lower the cost of materials is. like i said earlier the battle was lvl2 battle
