As summary describes, too much entities are spawning in a same area.

I was walking the nether and saw +10 endermen in a same chunk, just passed and there were no trouble.

Then I kept exploring and found a bastion remnant, decide to enter and found myself overwhelmed by +25 pigglins, got killed and lost all.

This is really annoying and alters the game experience, I would like to see it patched by the next bug fix update.

Thanks for the assistance.
