JC Daily Minor Exploit

[Wise]

found a minor exploit while doin JC daily q some time ago, if your bags r full and u r tryin to create item needed for quest, u'll get credit for craftin it w/o losing mats (because craft failed due to luck of free space in bags)after doin it u can easily buy required items from AH or get it from bank (if u got them alrdy) and finish quest.
i dont know, will it be usefull to some1,
