I'm done with my server but today a guy found a glitch to climb walls using blocks in World Guard regions which has Build deny. I think that happens because the delay of my server is high, but even when it's only 1 person online it happens. This is my timings: http://timings.aikar.co/?url=11409161 (I don't know how to read it) Is there anyway I can fix it? I think I saw a plugin one day but a months ago that fix this, but I'm not sure! Later will put a video in here if you don't understand what I'm saying. Thanks!
