I think i notice some bug at my inventory, and correct me if im wrong because im still new here at BDO.
see my inventory, there is something image of sulfur, and theres a label of "inventory expansion".
its weird, i tried to move some item, then my slot was suddenly decreased.
does anyone experienced / noticed that?
Perhaps your Value Pack has expired.
I also share the same thought as Jarette. New player has a free value pack (VP), but I forgot how many days the VP is.
You can check whether you still have the VP or not from the icon on the top left corner of your screen. See the screeshot below for a VP example
