"Mine Black Cave" is Disappeared!!

[jaejaehyun]

I've been playing Castle Story and I got a 'Mine Black Cave' from King's Keep.
I'm sure I clikced not 'sell' but 'STORE' because there is no more space in my area and also there is no reason to sell that.
But when I checked my inventory, the 'Mine Black Cave' is just disappeared!!
How come my 'Mine Black Cave' is disappeared?!
I'd like you to check this problem and restore this, please.

time it happend : 23th, November, 2:30 pm (KST, Seoul)

I found the 'dark cave' in my inventory.
I guess it's not go well to try to put in to inventory after choosing 'place'.
I was able to find it in my inventory only after reconnecting game(in case of iPhone).
I think it must be a bug anyway.
