Hello, after the latest update from rust and oxide which by the way good job FacePunch for fucking up everything but anyways. We are now getting a fail to call hook error. The shop still works but players don't get a notification in chat like usual showing how much and what they bought/sold. Here is the full hook error: 

(16:57:15) | [GUI Shop] Player: [Admins] Irish Selled Item: charcoal x2100000
