In which minigame/server does the bug occur: Parkour

Detailed description of bug: After being afk from school for 6 hours, I went to parkour and I heard in chat there was a new update in parkour, So I went there and there were new maps, I was so excited until it kicked me for flying, it did this about 1 second after I logged on parkour, it just kicks me, I don't know whether this is a bug or a glitch that sometimes occurs in parkour, but for me it's most likely to be a bug, I have Proof of this happening but the thing is, when I go to parkour it just kicks me for flying although I wasn't flying, I think it's a bug that I just found. http://imgur.com/Sod2MRA
