Running a Project Ozone 2 server for my friends, and I'm having issues with the server not responding. When one player is logged in, it seems to run perfectly fine. However, if two players get close to each other, the server freezes (CMD still allows me to type, but doesn't respond to commands). I can't even connect using 0.0.0.0/localhost. I've tried everything I could think of, and am lost on how to fix this issue. From the testing I could do, it seems like it starts when two players are in the same chunk. Friend thought it might be a memory issue, but I have 8gig ram dedicated to the server, and it barely ever goes over 3 in task manager. We're playing in Kappa mode and are almost to the Dire Crafting Table, so I'd hate to have to restart the world :'(. If you have any ideas, I'd really appreciate hearing them. Thanks!
EDIT: After it was frozen, I disconnected and the server eventually loaded like 5 minutes later and the console spat this out https://gyazo.com/6cfd2006ecf776ee45c0d383710dfbac
