I just opened my inventory to find in it, even though I didn't buy it and I don't remember seeing a random event. I'm not even sure cash shop items can be received via a random event. I suppose it's possible that a hustler box popped up and I accidentally hit "buy" instead of close...but again, I didn't notice that either.

So, if I did accidentally buy it without noticing (I tend to ignore the hustler ads), that's on me. But I wanted to inform staff about it on the off chance it was a random glitch that needed to be addressed.

That's the achievement prize for having 2,500 items in your wardrobe, did you get that achievement?

Ahahahaa, that explains it! That's hilarious. I'm so glad I didn't submit a ticket for this! XD
