When minecraft updated to 1.16.100, my worlds have been lagging very badly. I tried to switch hot bar slots, but it kept going back to the thing I was holding before. Mobs and players sometimes frozen, such as slimes jumping in place, or mobs freezing in place, but I'm still being hit from behind, even if it shows them somewhere else. Also, when I eat, I have to hold LT down for at least 6 seconds for it to actually show that I ate it. It's not just lagging for me, but all my friends. If you could help that would be awesome, Thank you!
