@452: Ok, let's start from step 1. My chat has nobody in it - thus, no chat history. That was part of what caused it. When joining the chat, since I have chat hacks on, it shows the message that they were loaded, which shortly after is cleared off and replace with the welcome message. Since there is no chat history currently shown, any attempt to talk will not show up until the page is reloaded.

EDIT: Yes, I am ensuring that the cache is emptied. And when I am unsure if my browser's cache is clean, I go into Chrome's web inspector to see if any API call to load removed scripts was made.
