I just created a new realms world for my friends and I to play on, and not 5 minutes into playing, there were only 3 of us online at the time, it gave all off us the "timed out" message. We tried to get back on for a couple hours and it stayed down, but when we all relogged, it put the server back into default state as if it had just rolled back. This is unacceptable as this is a thing that we are paying for and it doesn't work. Only luck I had was turning off the mob spawning gamerule, and it worked for about 30 minutes until someone came across a spawner, which proceeded to give the timed out message and rollback the realm. Something to do with the new rendering system and the mobs being loaded is the best idea I have of why this problem is occurring. It happened a few times in 1.16, but in 1.17 it is way worse.
