Wrong Location in the console / Extreme FPS lag + chunk updates

When this glitch happens , the fps drops from 60 to 5 fps .
I observed this bug in the console , it says : Wrong Location! qa['Bat'/1004, l=Myujinn's LP' , x=351,75, y=64,10, z=258,75]

Apparently , that's a bug with Bats . Sometimes , it stops and when I reload the world , it happens again . It's a really annoying bug , thank you if you can fix it !
