Game stops functioning properly after a while

[Hongmoon]

It's never happened before until today, but for some reason it won't let me use anything. I can access the warehouse just fine, but trying to put things in marketplace doesn't work. Teleport doesn't work. All of chat stops working except for system messages. I can still switch channels just fine. I can use f8 to go cross server, but when I go back it' still the same. I have no choice but to exit the game and deal with the retarded queue.
