PS - This was on the realm world that we have been having some extreme problems with as well I might add.
If you continue to have this issue where rubber banding latency happens and you lose progress. The easiest solution that you can do currently would be to make sure before everyone enters the nether is to make sure that you back up progress prior to entering the nether. At the moment I'm not really sure how the backup process works on Realms, but there seems to be a time frame involved that it saves during active play. For example every 15 minutes or 30 minutes the best way I know is to get everyone on board before entering the nether, make sure the save is there, have everyone log out and log back in and then enter the nether.
Me and my daughter played last night and she wanted to go into The Nether, so we both logged out confirmed the save was active within 5 minutes of logging and then we both entered The Nether together and it worked perfectly. No lag. Rubber banding or progression loss.
Also. I have downloaded the Realm local and ran it. And it does NOT drop like this when ran from my PC. I can zip into the nether with no issues. Forget about me mentioning Linux. As my rig is Windows 11 based. And still does this. There is not specific trigger other then Gearing up to enter the Nether. Or to jump Nether portals (As we have several set up to get around faster) With One Main Portal in my main base that is link to center of Nether spawn area. All the rest are properly linked and mapped out so as not to interfere with each other.
The ONLY reason I sub to Realms is because I want me and my Girls/kids to play together and they can play when I am not on line. So that progress is saved. Otherwise I would run local and be done with this.
Running Windows mainly. Updated to newest version when I reopened this ticket.
Has been happening to me here at my place and to my Girls on Chrome Books at their place. All three of us are on 1.21.111…..
I tried Linux to see if the problem would resolve. It did not.
When we enter the Nether. Run a few blocks, whether SOLO or with each other. We disconnect. If we wait 20 min sometimes the server catches back up and lets us continue where we DC’ed from. Otherwise IF we try to enter the Game again it just loads the latest save which is entirely random as to when that save took place. 5 min ??? 35 min ??? no one knows specifically but it appears as to rubber band us Back in time to previous saved points.
If we say screw it. Log off for about a Hour or maybe 20 min. Sometimes the server adjusts itself and fixes itself. SO that we regain our proper point in time. ALSO noticed that if we switch Servers, Sometimes this fixes the issue however the Game will get STUCK on a server and refuse to reset to another. This is both in the Realms settings panel before logging into game and Also once logged in world.
Also…..I am seeing fairly new posts both here and on Reddit suggesting this is a ongoing issue that Mojang is aware of but seems to be somewhat at a loss as to how to fix it. It seems from my end to be pointing to how the game saves progress (Though not directly) and the transition between the Over World and the Nether. NOTE…..this does not happen in the End. It seems specifically Nether and Over World link up related. Almost like we zone into the Nether and the game pushes us out of bounds.
It is infuriating.
This is Still broke. The only work around being that you need to set Realms to SAVE upon Nether entrance. This is a damn joke. And is NOT effing resolved.
Having same issues. And tried similar fixes as OP.
Seems to be closely tied to Nether Portals as it happens all the time to me in the Nether. Overworld seems to not be as bad but has happened. ALSO I loose progress. Whether it is mining progress. Gathering Progress Building progress etc. It will randomly reset. Worst time it happened was I lost over a hour of play time. Rubber Banded me back to a previous save type point.
No Mods. No addons. Just Plain old MC. Never had cheats or nothing enabled.
Basically what I said above. Each of you need to log in alone and go through the Nether Portal and then AFK until the save happens. Once that happens you ought to be able to log out and let your next friend in line do the same thing. If you're unsure of things saving correctly you can agree to meet at your main base. The idea being that I think there's a problem with the way the game is saving on the Realms server and the time frame between saving and the fact that people get scattered. For example if one of you is in Overworld and the other of you is in the Nether, there seems to be some kind of conflicting issue where Realms does not like people in both places. It is definitely tied to the way Realms is saving the info for the world information and also it is tied to going through the Nether Portal.
It's funny it doesn't seem to happen in the End much, that I remember. In fact it hasn't happened now for a while to me and my kids playing. And we have since defeated the Ender Dragon so there might be a correlation there.
Keep in mind the world that this was happening on with us we have about 12 different portals set up north south east and west with our main base portal in the center and almost all the portals are over 800 blocks away from each other in the Overworld so as not to conflict with each other.
We got to the point since it's just a three user Realm and not the 10 slot Realm we got to where before we go through to the Nether we prepare and then we log off before we go in and then we all log back in this forces a save I believe and for whatever reason seems to clear cache.
I live by myself and my kids live with my wife so we're not on the same network at all and I am 100% certain this is server side because I have downloaded the realm world and hosted it local and its not had the issue.
