Respawn button doesn't fully work due to lag.

Please fix this performance issue, man. It is doing my head in. I pressed the respawn button 5 times after diving off a cliff because I was lagging so much. It wouldn't let me spawn back in so I raged quit. So much lag when loading new chunks. Fix it in 1.18.1 or else I won't be able to play my favourite game anymore. I'll just be done with it at that point.
