Hello
My server has extreme lag and after I do anything it basically goes back in time, like after digging a block it comes back and I don't get it. It's annoying and It's just me and my friend playing. I'm assuming it's my mods but honestly I know nothing about this kind of stuff. Here's a link to my log if anyone can help that would be very appreciated
