It's freezing while I am walking. I don't do anything specifically I just walk around the map and it freezes for like 1-2 seconds. I am playing on 1.16 pre2 (using that version of the map as well) and I am also playing on a Fabric server that I am hosting.

Do you possibly need logs to help you fix it?

No, I approximately know, what is the problem. I'll try to fix it with update to the pre3.

Does problem still exists?
