Depending on how you typed in the seed, Minecraft could have interpreted it as a phrase and generated a new seed from that. Copy and paste might do this as well, if you copy from a non-ascii source with some formatting commands in there. Best bet is to type in the seed manually using only the number keys on your keyboard.

If it's your single player world, no one but you can make that determination. On a server it's a different story and would be something the players of the server or the server owner would have to determine. A server I used to play on posted the seed so people could create single player worlds of it and find stuff easily without having to search forever creating new chunks that would just take up space. On other servers that would be considered cheating, so they don't release the seed. All depends how you want to play.

Looks like a problem with the colossal chest config file:

ConfigLoadingException: Failed loading config file colossalchests

You can try making a backup of the config file somewhere, then deleting the copy from your mod pack install, and see if it gets generated automatically, that might work.

Random terrain generation, it means nothing.

Increasing tick time will fix the symptom but not cure the disease. It's still a good idea to audit all your storage systems and find out what was causing the problem in the first place.

Looks like a problem with sophisticated core which might be an inventory mod? Something in there about inventory and hoppers, so my guess is, if the server had been running fine, and now isn't, that some automatic process like a mob farm has backed up and is jamming an inventory system and it's overloading the server, as a tick is taking longer than a minute, so it shuts down. See if you can log on for long enough to find the issue and if not, there are server commands that will purge dropped items (might be the issue, just a guess) and in an extreme case, use a map editor to delete the hopper in question, if that's the cause, or even worse, delete the entire chunk and take the hit to the lost items.

There is a bug(s) listed for this on the tracker, https://bugs.mojang.com/browse/MC-95529 and https://bugs.mojang.com/browse/MC-91121 the usual advice being to delete the player .dat file and see if that works. Since you've already had that done, probably not that. Something else I've found is it might be a DNS problem, https://support.aternos.org/hc/en-us/articles/360026805072-Connect-to-your-server most of that is specific to that server provider but the advice at the bottom about flushing DNS cache and changing DNS server might help?

You're probably better off asking on a dedicated modding forum, github or reddit sub like https://www.reddit.com/r/MinecraftMod/ or https://www.reddit.com/r/forgemodding/ as this forum is for general Java support, not actual mod coding questions.

Sorry for the delayed post, long weekend, but yeah I have no idea, there are too many variables and it could be anything.

Yeah it's strange, are you running full screen or a window? Have any other software running, especially one with a screen overlay? Just grabbing straws here, not really sure if it could be anything like that.

Someone else reported the same thing here

aside from changing mipmaps and being sure your drivers are up to date, not sure what the issue could be. Is this on 1.20 ? I wonder if they did something with graphics in the new version. Hmmm I also wonder if it's something in the graphics card settings outside the game like Nvidia has some anti-aliasing options that might look good in other games but in Minecraft look like crap.

Interesting, could the direction travelled answer why that one time the game crashed and the water pond disappeared? Since the first time I approached from a certain direction, the pond was generated, but after the crash and respawning, I didn't "approach" at all, but spawned directly in the chunk, and there was no pond.

If this were the case then worlds would be totally different, including biomes and terrain, you may as well have used an entirely different seed, and it is highly unlikely that they would make such a change to the built-in RNG, even as old and low-quality as it is, as far as I can tell the last change made to it was all the way back in Java 5, the oldest version any version of Minecraft can run on (up to 1.5.2) and that only changed how a random seed is obtained (it used to use the system time but now uses a more complicated formula):

<snipped for brevity sake>

Yeah not sure what exactly is the cause. I know from screenshots at the time that everyone who posted about the Glacier seed ( I think it was beta 1.7.3? Seems to be about the right era) that certain trees and the water spring on the floating island spawned in the same spot for everyone, or at least everyone who posted screenshots. I haven't tried generating that seed in beta 1.7.3 on the most recent install of Minecraft but I know generating it on the "new" install where you can pick whatever version you want didn't generate that water spring and trees were different. So at that time and place it seemed that it was always the same but then never again after that.

But I also know that some things generate differently within the same version. I was playing on a world where a pond generated just below the ground surface with a small opening to the air. I was in the pond mining coal or something when the game crashed and either corrupted that chunk or didn't save it, but did save my player position. Opening the world again, I was where the pond had been but it didn't generate this time when the chunk was created again and I was stuck underground inside the dirt.

I don't know about leaf decay but I do know other things change somehow when running an older version on the new setup. One that comes to mind specifically because I tried it once is the old seed "Glacier" on one of the beta versions (I think, might have been alpha). It was a popular seed back then. You spawn near a floating island, and in the original version, that island would have a water spring flowing from it. In subsequent versions, that spring would no longer spawn. The island and the rest of the landscape would be exactly the same, just water springs and as I recall, tree positions would also be different. I put it down to something in the random number generator outside the Minecraft code was causing it, but then I'm no Java expert.

How much system memory do you have and how much is allocated to Minecraft?
