So my server was doing great. it was 1.7.10. we decided to make it 1.8, so we downloaded all the files, put them on a test server and converted everything to 1.8 It was all great, the server runs 1.8 great. However, when people join, they get stuck in some stone that to my knoledge is under spawn. They cant see much chat, and after that over, there is luge lag spikes. Im guessing it all it because of lag. It says im getting 20 tps in /lag, and i have clearlag to keep things cleaned. Please help me figure out the lag. If this doesnt fix, im probably going to delete my server.
