Exchanging ETC items at this particular NPC disconnects me after 2-3 of exchanges, no matter the item or the speed in which I do it. I am currently exchanging Star Pixie's Starpiece and the game keeps kicking me to the login screen with the chat box stuck glitched on top of the middle of the screen where I need to type my password.
It appears you seems to be getting the error from clicking on NPC's too fast. This happens to all NPC's, and more likely when there is lag issues. Take your time on clicking the NPC's.
I already mentioned in my original post that the speed at which I was exchanging did not matter. If I do it fast, it disconnects me after 3-4 exchanges and if I do it "slowly" it disconnects me after 3-4 exchanges.
