Hello 

I have a Multiplayer server that I had for 3 days and since the update on 1.16 and 1.16.1 its been nothing but lags everywhere now I have a creeper host server but It's nothing wrong on their end its Minecraft itself as its been reported on many different servers that since the update its been hugely bad and laggy. 

Not only that some items go missing, blocks go missing when built, the day and night cycle on multiplayer goes wrong everything is bad when it's on multiplayer. 

1.16 - causes lag 

1.16.1 causes Items to go missing, blocks gone, cant work, huge lag, etc, etc 

SinglePlayer is fine its just Multiplayer 

Thank you for your time
