it's a bug that nexon left behind
the coin cap on santa boxes is 10, but if you are lucky to get a stack of 2 coins on your 10th coin roll you can get unlimited coins
Thank you, anyway, i can not open more than 10 coins from santa boxes, it fixed.
I guess the reasons why cause the bug are:
First, since change potion( turn into a small animal), but CMS use potion to reach sss rank.
Second, windowed model for 1024x768, someone said full screen for 1366x768 is more smooth than windowed.
