Hi. I've got a server hosted on my own computer, with 2 gigs of ram allocated to it. When I connect to it, it works just fine, but when my friend tries to connect, it has a weird glitch. While everything seems normal in-game for me, often-times all animals and mobs are frozen for them. They also get teleported back to their spawn point quite frequently, and cannot see my in game character, though I can usually see theirs. 

Both computers are connecting through the same network, clocking download speeds of 35 mb/s and upload speeds of 10 mb/s, so it shouldn't be a problem with the internet. We are also connected using Hamachi rather than port forwarding, which has never given me a problem before. 

Anyone else experience this/ find a fix for it? Any help is appreciated.
