MakoKing Posted November 3, 2025 Report Posted November 3, 2025 I will start by saying I do play with mods, but the confusing part is I haven't updated or added any mods that would edit world generation. The worst part is it feels RANDOMIZED, sometimes I'll get long stretches of land that works perfectly fine and then out of nowhere it's like my world forgets what seed its using and just invents a new one on the spot in other areas, loading in an entirely new world when generating chunks. I've added some pictures of the chunks as well as various locations on my world map where you can see the chunks glitching out and just making a "new world".
MakoKing Posted November 3, 2025 Author Report Posted November 3, 2025 Did some more testing and now I'm more confused than I have ever been. If I make a new world in singleplayer and explore around, it works perfectly fine, even so much so to the point where if I set my movespeed to like 4 or 5 and fly around it still loads chunks without any issue. HOWEVER, as soon as I then move that SAME WORLD over to my server and run it there, whenever I walk up to new chunks the server will simply not load the chunks for a minute, resulting in me staring into a white void at the edge of a river, then start loading the chunks before breaking halfway through and loading a new seed. At least I THOUGHT it was a new seed but instead it seems to just be loading the wrong values, seemingly forgetting its supposed to be loading a mountain and then halfway through deciding to load a plains or a plateau for example as it seems to still be loading the same biome or region.

I hope it's not related to internet. OTOH, it could possibly be related to the power of the computer. The first question is always about mods, but the OP is aware of that, so.... ugh, I dunno.
LadyWYT Posted November 3, 2025 Report Posted November 3, 2025 Which game version did you create this world in, and which are you playing now? This kind of glitching looks very similar to some of the issues that were had in test candidates for 1.21. There were some tweaks made to terrain generation, and the chunk blending had a few hiccups. If this is a world that you created in an rc candidate, or if you're somehow playing on one of the rc candidates still, that's probably what's going on. However, you also mentioned playing with mods. I would check your modlist to see if there is anything that could interfere(like mods that alter terrain generation), as well as test the game to see if you can repeat the issue in vanilla. As always, make backups of your beloved worlds before testing like this. If terrain is still generating funky in vanilla on the latest stable release, then you've probably found a bug and should go report it on the bug tracker. 1 1
Thorfinn Posted November 4, 2025 Report Posted November 4, 2025 Alternatively, are you absolutely certain that your server is running 1.21? Sounds like one or the other is not.
LadyWYT Posted November 4, 2025 Report Posted November 4, 2025 (edited) Looking at that map again, are you using a rivers mod? Like this one? https://mods.vintagestory.at/rivergen Looking at that particular mod's page, it looks like there's a known issue with chunk generation when updating worlds between game versions. It also looks like it's incompatible with Better Ruins and will cause similar issues if you try to run both at the same time. I'm guessing that's probably what's caused the issues here as well. If this is the case, I'm not sure there's much you can do to fix it, other than adjust your modlist, make sure everything plays nicely together and otherwise works as intended, and start a new world.

MakoKing Posted November 4, 2025 Author Report Posted November 4, 2025 (edited) @LadyWYT I am playing on 1.21, not any of the rc versions either. I am playing with mods (including the RiverGen) but im not sure if that's the issue since I haven't updated or changed any of the mods nor the game version and they've been working perfectly fine so far, like on the singleplayer world I made last night to test on where the chunks loaded perfectly fine without any issue but then broke as soon as I ran the world on the server @ThorfinnWhen I run the server exe thing it sys "Server Notification: Running game version 1.21.0" so I'm assuming it's on 1.21.0, I don't fully know how servers work tho so that might just be commenting on MY version of the game rather than the server for all I know Edited November 4, 2025 by MakoKing
