There can be several reasons why the cosmetics are not displayed ingame: The most common reason is that you are not connected to the database or that you are using an outdated version of the mod. Please always make sure that you installed the latest version of the OldAnimationsMod. In the gadgets menu you can check whether your database status is "CONNECTED" or "REFUSED". If the status shows "REFUSED" simply click the button below to reconnect to the database. Another reason may be that an error occured during the payment process. In this case please contact us via mail, twitter or discord with a message containing the transactions ID of your purchase.
