I made a copy of Malgus Reborn Armor Set from Collections, boots were missing.
Since then, Collections is corrupted and every page is blank.
Since then, there is an empty spot in my inventory (I noticed it when I sorted by quality and one random spot remained empty between items).
If i try to put an item from Legacy bank in this empty spot, I get an error saying "Item is bound".
If i try to put an item from Personal bank in this empty spot, this empty spot transfers to the bank (Collections remains bugged).
