7) Limited Items Box to level 60.
Taken from HERE
To put it short, Items Box is only available for players whose level range is 1-60.
If your player level exceeds 60 (e.g. you're lvl61 player) the Item Box comes unavailable to you.
Oh, Items Box is also unavailable to me since i'm lvl78.
OMG!!! They delete all our tokens for a reason I never understood, and they compensate us with a gift that is limited and they tell us that at the bug reports under a hidden "spoiler"?
TROLLING LVL: ∞
There is no obvious reason to limit this since there are weapons until level 70 and there should be an obvious warning somewhere since they gave a gift that is limitted...
