1.20.1 Forge 1.20.1 World Suddenly not Loading

[Fehenrin12]

I created a modded Minecraft pack and subsequent server for My Fiance and I to play on, we are both new to modding, and have no experience of what mods go together. We gave it a shot and made a pretty good pack, based on some mods we saw previously in All The Mods 9, plus some other building and fun mods. Everything was great, server was running for 10 days(?) and went through multiple subsequent restart cycles (wasn't online 24/7). We were wrapping up for the night, I did /saveall in game, and the command said the world was finished saving. I then did /stop.

Following morning we attempted to start the server and it will not get past:

[19:25:04] [Server thread/INFO] [minecraft/MinecraftServer]: Preparing start region for dimension minecraft:overworld

I attempted to take out the world, and load it on Singleplayer, however same issue, world wont load. I deleted the "serverconfig" directory and it will also not load. I removed the world from the server, thus allowing it to generate a new world, and that worked fine. But our current world will not load anywhere.

I am aware of some errors in the logs due to some mismatching, and incompatibilities; I didn't know what was strictly client-side, and what needed to go onto the server, I also didn't know what performance mods did what, so there is a potential multiple were doing the same thing, however this shouldn't be responsible for the crash, as no new mods have been added for atleast 10 restart cycles and everything worked smoothly. I know there is an error about Canary conflicting with Better Chunk Loading, however that error has occured since the beginning of the server and nothing new.

It is to be noted that there isn't actually a crash happening.

If this world is corrupted, is there any way to fix it? I have a backup of the world from 4 days ago, but I also dont want to have to roll back that far, I would really like to deal with the issue at hand.

Same issue without the mod Cupboard?

Yes. I disabled Cupboard and all the other mods by that developer


I really care about this world, as it isn't just a world to me. There's losts of monuments already. Really hoping to get it loading. It's weird that it could be a mod doing it, as I had stated that no mods had been modified for a few days, and still the server was loading and restart fine.

Put these mods back in and also ad the debug.log

By the way, I don't think I made this as clear as possible. When the server would not start, I copied the world from the server and am now trying to load it in from Single Player. When I said I removed the mods, I meant I did so from the client, as the server was out of the picture, as I was loading the world locally from single player. The log I provided before was from the server, but same thing happens on Single player.

I did disable all of those mods in the screenshot, and the world would not load past 14%. Adding them back i'm loading up to 80% and then nothing.

This is the full startup log of trying to join it from singleplayer: https://mclo.gs/Or8U7N6
And here is the debug.log from BEFORE when I was trying on the server. https://mclo.gs/2uTQucK
