I logged after the patch on Friday and ran some CICP for a bit, and hit a Jackpot or two that had cakes slices in the lootsplosion.
Today, I've been doing some prestiging in ICP and have hit multiple King's Ransom Jackpots and have had 4-5 runes drop instead of the cake slices.
Did the Jackpots get live-tuned for dropping too much cake?
