Bought a Tier 4 Box with Full Inventory. Received no items.

[Flynn]

As the title states, I stupidly purchased a tier 4 lockbox while my inventory was completely full. I received no items, and am out the 64 keys. Anyone else mess up like that? Any way to retrieve them?

UPDATE: Oh sheesh. Just checked my claim items section, and the items are sitting there. Apparently, I've accrued a few items in this manner. Derp. Hope someone else stumbles across this thread if they encounter the same issue.

I do lose items from Arkfalls in this manner. They do not go to my claim box

This also happens with any item if you have a full inventory, i have only once ever had an item go into my claim box, moral of the story here is make sure you have some space till they fix it!
