"Full Inventory" - anyway to forcefully activate it?

[xWildhx]

So i have coupons from spend event that i want to send directly to mail, however, sneaky r2 doesn't want me too. I have full inventory(+vault) but I still dont get the message "full inventory". so the game doesnt send anything to mail like it normally would went yr inventory is full, instead, the items that are "extra" are just hidden, so next time i use/remove item from inventory,
those "hidden items" magically appear. So anyway to go about fixing this?

Stick the items in your vault, then ask to be kicked from your guild (spend your contribution first). The contents of your vault will be sent to mail.

And coupon will expire in mail.

@op sorry dude, i can't think of any way to save them.
