Ravagers levitating?

Ravagers can levitate? I made a drop 3x3  at a raidfarm and they keep levitating above it.  It was 2x2 before the update and noticed they did not fit in that antmore?  tried to fix it  but same problem at 3x3

 This is just 1 of the big bugs there is the game is not fun anymore  lag bugs  stupid updates that ruin worlds

Wth is wrong at Mojang?
