Just me and a friend were online and the server was receiving 6 second lag spikes every 5-10 seconds. Tps always says it's at 18.50 I think it's stuck and needs the plugin to be reset. A restart might fix it though. Anyways, the server feels about 5-7 tps-ish
I removed a base from a player who was duping (over 12k tile ents in his base). Maybe this reduces the lag spikes, let me know.
