In our minecraft world when we updated to 1.18 the lag (that we had before) had gotten so bad that we couldn’t break blocks ,place blocks or even drop items. So I looked around and found nothing that could lag out the game so much, but I did find that the lag was only in one area. After a while The system had updated so I thought maybe the lag was better or gone, but it was not, and then I noticed that every single mob (except for two villagers) had disappeared and I have no idea why. So please help us and fix this issue.
