Where it happend: Trial of Chaos finished Map 9

Circumstance, Inventory is full except 2 open slots.

A pair of boots in the Inventory was exchanged with Corpsewade.

*Expected:* usual logic is, that Corpsewade is added into the same Inventory slots where the exchanged boots were + the Support Gems are added into the open Inventory Slots, not fitting Support Gems drop to the floor.

*Actual:* Boots from inventory are added to boot slot, Corpsewade + Support Gems is vanished. Not on the ground, not in the Stash, just gone.

i walked over the whole map accessible to me, no Corpsewade laying arround
i cleared inventory, walked arround
i tried logging out and in again - same result
finished trial - checked Stash, no Corpsewade in there
