Often when I use my nether portal it will disconnect me and will send the game back to my last autosave, affecting everyone else who is playing as they get disconnected too. I am the only one on the server who has this issue, everyone else can move freely through the portals. I have lost countless inventory and other people on the server have lost hours of work too as we all get reset back to my last auto save, for exampled today there was myself and one other on the server and we lost 1.5 hours worth of work because I tried to go through our nether portal. Is there a fix?
