I'm really enjoying the game so far, but one thing is really becoming annoying as hell. Whenever I need to sell off my inventory to a merchant I right click items to sell them. However, the process feels like there is some kind of delay. I need to right click and then wait before it sells. Sometimes the item picks up, sometimes it doesn't do anything, and sometimes it sells.

Why is there lag for a simple offline merchant transaction? I should be able to right click as fast as my hand is able without any delays.

What gives?
