Yep, it doesn't work unless you have space for the goods to gain them. Prepare for lots of blessings, and spend some ntgs on your coalitions I guess.
They have run events with these requirements before, and they have always been badly calibrated. The last time around I think the reward was a diamond mine, which I didn't want. The pirate camp is a better reward, but basically unattainable. Level 3 in cold war is 175 goods, and I am unlikely to get that. 445 for level 5 means 60+ a day? Not going to happen.
