My storage has only 16 slots, and I am not sure if this is the maximum amount of slots storage MapleRoyals can have. My inventory, however, is maxed. I tried purchasing the Increase Storage Slot in Cash Shop (the buy options for the other inventory slots are greyed out), but nothing happened when I did so. There were no deductions of NX. And when I tried to purchase another Cash Item in the same session, nothing happened as well, until I leave and re-entered the Cash Shop.
