Hello, I started my server and a serious chunk bug appeared... strange... Some chunks are at the wrong place (houses cutted off, chunks stone walls, chunk multiplication...) I've taken a screenshot of the "chunk multiplication", it's really really strange... Also, i have NO errors in the console... Solution ? :s more screens Solved ! SpoutCraft launcher causes this problem, for the others, you may disable chunk caching in the server plug config (spout)
