I might be able to attach a video but i am not sure
very far, i was around 30 blocks away from the middle of the world and I teleported at around 7000 blocks away
I am having the same problem, i've played minecraft a lot and I have not seen anything like this, the most frequent mob i see spawning is the creeper. I will see about 10 creepers every minute which should only happen if you are playing hard mode. I play on multiple editions and mainly PC the other editions never have any of these problems especially Xbox edition. I play pc a lot and i've only seen this happen this year and I have not been able to get far because I can't get diamonds with 900 mobs spawning all around me killing me instantly. i triple checked the difficulty and it is set to easy.
Do the monsters spawn in the world for a split second on other difficulties rather than peaceful?
I disabled spawn-protection and still get this error and many members of my server report to me that they sometimes can't destroy/break/interact with blocks, these warnings spam my log a lot. My server is btw running on MC 1.16.5 with some datapacks that I know aren't causing the issue (the issue has been there even before I added them) I hope this gets fixed ASAP
