When someone enters the Nether, after a certain period the realm disconnects and kicks out all players. When you manage to reconnect, the realm rolls back for at least 30 minutes. 
 
I have read many posts about it for other previous versions as well, but I haven't found any about 1.17 or a possible solution to the problem.
Can you help me solve it? A realm where a rollback happens at least once every day is not good for players.

Thank you for considering my report. I hope a solution to this problem is found soon.
