i hope this helps, its the best (possible) fix and easiest i have found so far. every session you load (this is mainly for the person hosting) use the console type "dm" for debug menu as most of you probably already know, open the pause menu, then hit recalc stability. Everytime this has fixed my ghost blocks for the current session i simply do this if i encounter them when loading in. sometimes i get lucky and dont get them at all, also without disabling pois so i still get to keep my render distance etc.
ive noticed this is a ram issue. whenever i had multiple things open such as google chrome, fl studio other ram intensive programs i was constantly getting them, everytime i load the game now with no other programs running its kinda hit or miss if i get them say like 40% of the time im good.
again, possible fix. worked for me but no guarantee it will work for others, just a possible solution
