[QUESTION] Level sync between players

[Luchezr]

Let's imagine, level - Floor is a lava. When 1-st player open level, lava is on level 10/10, but then connect and open level another player, and for he lava is on level 10/10, but for first player it's on level 8/10. How I can make sync between players, when for 1-st palyer lava is on level 8/10, and for 2-nd player it's on 8/10?
