Block updates not immediately rendering

Bug Report

I'm running a multiplayer server with the "Bedrock Your World" game mode. After a while of playing/base building, visual block updates started being wonky for all users (three on both Windows+Linux). When logging in or going between dimensions back to the home dimension, around half the blocks at home are invisible. When interacting with a block (e.g. pouring iron into a melter's ingot mold), the effect is invisible until you perform another action, so everything is one visually one update out of sync.

This only affects rendering, not collision detection.

Expected Behaviour

Example of the rendering glitch: https://imgur.com/a/XVbwRSl

There's a block (a ME Fluix Cable) right there that I just placed. I can see the outline while hovering over it, but it itself doesn't appear to me (or any of the other players) until I place a second block.

I had the same issue. Removed the uncrafter and the automatic drier and that seemed to solve the problem completely.
