Hot Week: 2/23 – 3/1

Made 13 spaces in Use and got it to open.

*facepalm*

Edit: That's not enough. That character also has 10 empty Etc slots and 20 in Equip.
I tried on another account, but couldn't make enough Equip space (only managed to get up to 10 slots). Or something. Anyway it still wouldn't open.


Second edit: The research continues. It's starting to remind me of the infamous Error 38 bug.
Got the box on a third account, who had 2 free Use slots, 43 free Equip, 31 Etc, and 45 Setup.
It wouldn't open.
Cleared another 4 slots in Use (total of 6), it opened. (Was too lazy to try after each slot, so I don't know whether 3 or 2 or even 1 would have been enough).

Seriously, Nexon...
