Ever since they changed blue diamonds to the topaz graphic it just shows as nothing but the small number in the bottom right hand corner. All my other pcs show the updated graphic... What gives??
At the launcher screen go into Advanced Options (gears icon), select Validate Game Assets and let the launcher scan your files. See if that helps.
You must be using a custom ui with a custom inventory. You need the updated dragitem files placed in your custom ui folder.
