The Pet Boost Package that was discounted until 9/10/2018 keeps telling me "You have too many cash items, please clear your cash inventory". I only have 116 items and even when I took some out it still would not let me purchase the box!!! Now the sale ends in a day and I also see that when I hover over the item the price on the item does not match the sale price. It says the box is 8500 instead of the sale price of 4250. I really wanted this on a few more of my perm pets =[. I was able to purchase the box on other characters until about fifteen min before the end of the day. I'm so bummed!!! Offer again soon please and fix the inventory, glitch, wrong price error!!! Just seems to be an issue with using maple points to make the purchase. I loaded some NX on my account and could purchase the box. Tried again to use the maple points and got the same error about having too many items in my cash inventory. Please Fix!!!
