I was at /warp gate2 walking around and then some glass wall kept appearing and reappearing in the gate. (It was like rainbow or something) I was punching at it with my sword and then I got kicked. When I log in it says I'm banned for "Unauthorized Client Modification". I don't know if this is a glitch or if what happened. Please help me as soon as possible. Thank you.
