Steps to recreate:

1. I was trying to find some better items for my Miscreated Monster

2. My inventory was full: 700/700 and I had some items in Inbox also

3. I had a 5 stars perception chestplate (with HP%)) which I upgraded to lvl 16

4. When I tried to replace the chestplate from Miscreated Monster I got a message that 'Inventory was full '

5. I tried to make more space in the inventory in order  to be able to replace the chestplate

6. When I searched again for the chestplate, I realized that it was missing.
