Here's the thing.. Whenever me or the people on my server try speaking, there is nothing in the chat. When i try taking fall damage, i take none and neither do they. When i break blocks, the drop is instant, though. Also, whenever i try commands, it just says "Error: null". This just happened suddenly.. I had this problem the first time i set up my server and then i re-created the world and now it happened again.. I do not want to restart my world(who would?). Anybody else having this and know how to fix it? Also, in my serverlog, it keeps showing this up every time somebody in my server moves even the slightest bit.This just SPAMS my server.log. Any way to get rid of it? EDIT: This also happens whenever somebody speaks in my server. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
