So, my server has been playing up all night. People could connect, however it was extremely laggy and players could not type, or move. We have had some issues with lag in the past few days, which have been resolved. Also, there seemed to be an object that was being constantly summoned onto the server. We decided to then disable command blocks, but still the lag continues. When I finally could get off, I looked at my game log, and took a screenshot. Any help would be greatly appreciated, thanks!
