Literally about 15% of people who purchase through us come to support and say: “Help! I can’t build or destroy anything on my server! The blocks disappear and come right back!”.
Fear not, it isn’t lag. This is because on the default Minecraft server you are unable to build near the spawnpoint. Move a good 50 blocks away or op yourself and try again… it’ll work just fine.
Some mods remove this limit. Thats probably why most people are expecting to be able to build anywhere. Good luck!
