One of the items in my shop increases the amount of messages a user can hold. On my forum Admins can have 300 messages. However, I bought an item that increases it to 600. The amount and the bar in the inbox shows that I can store 600. However, I just hit 300 and now it's full. It's telling other people that my inbox is full. And yeah... the bar is only half full... It's like it shows you that you can have 600, but you actually can only have 300.
