I resently had a problem with my survival server where thousands of pigmens came out the nether portals and made the server crash every time me and my friends joined . I later found out that one of my friends set the tick speed to 1000 witch made all the pigmen spawn but also all the chicken farms ect... i tried changing the tick speed back to normal but the sever commmands do nothing for example when i /kill nothing happens so i ended up putting de server in peaceful to try and kill all the mobs but now when i join nothing .When i break blocks behind torches the torches levatate and redstone stuff dosent work such as presure plates and it seems that nothing is loaded for example no chunks load when i go out of where i last respawned and when i join the server i get kicked in a mater of seconds with a message in chat sayng ''the server you were previously on went down , you have been connected to a fallback server a''
PLEASE HELP
