how i got the bug and lag i dont think i should put since its something to do with what the game consumes and im sure that you guys could fix it so lets start
Step 1: open mineplex server eu.mineplex.com then head to skywars
Step 2: after i had fun playing i went single player survival and play some solo adventure in survival
Step 3: i fall and lost harts as well as lost hunger i get food "i tried many types of food after i experienced the bug still didnt work" and when i eat it just stays there showing that i am eating and nothing is happening and it pretty annoying since i want to recover health.
Step 4: i searched up and there many bugs in 1.9 so it was advised to just stick to 1.8.9 and thats what i did
1.8.9 works pretty fine for me no lag as 1.9 and i coulld eat food in survival or on the server without experiencing any bugs which shows 1.8.9 has almost no bugs for what i experienced

So dear MC devs or bug fixers i ask you kindly to improve performance i have i7 processor and 4gb ram and intel hd graphic 3000 which pretty much meets the requirements and windows 10 and as well as fix the eating bug which i experience on servers and singleplayer
Thank you for your time reading this
