Skwisher This has probably been said before but I couldnt see it on the forums and its an annoying bug that has to be fixed. It only seems to happen in the towny world, but whenever a break a block I always have to brek it 3-5 times before it actually breakes. This gets very annoying when I'm trying to build my new home it it would be great if it could be fixed.The Skwisher
Klitch It's block lag. Not a glitch. fuzzlr and the other admins have been trying to fix lag for ages.
abbythrowsstuff This is lag and can be expected on any server with a daily population of over 100. Please be patient, sometimes it will spike and that can be annoying but, lag is inevitable. Try anti-lag modifications like Optifine
