bought that item from the itzel vendor in verdant brink, noticed it didnt ping any unlock on the side of my screen so i went to right click it to view what collection it was a part of. that crashed the game. 3 times I tried and crashed the game each time, mousing over the item does not crash it only right clicking it.
Most wanted in game additions: Beastiary, readable books
