Your username: Pudding_McStubbs In which minigame/server does the bug occur: MF1 Detailed description of bug: So, I was inside a MineFighter room ready to start the match. My friend said "ih" then "hi" to correct his incorrect spelling and just a minor correction. So, I decided to say hi back. I said "Hi." and at the exact same time, I got a message saying "Do not send the same message twice." BEFORE my message went through. Maybe, I had already said "Hi." and it glitched and let me send the message anyway. OR, it may have just randomly sent the message. What's weird is (like I said before), it sent the message BEFORE I sent "Hi.", but at the exact same time as I said "Hi." This is probably the longest and most detailed bug I've ever posted, but here it is. Take a look at the screenshot and it will show everything.
Did you say "Hi" in the lobby BEFORE you joined a room? Joining a room is like joining another server...ish. So maybe that's what happened, I don't know.
