I don't understand what happened, and I didn't click or do anything because I was doing stuff in a different tab and when I switched back, I got this?

That's weird lmao, I have no answer to this. Never seen it myself,

Late reply but this usually happens when the client is trying to load an old client file. Logging out and then logging back into Habbo should of solved this issue, or simply fully reloading the client rather than clicking the back button. :)

i just reload and it starts working again :)
