      Server Move   09/13/18

      I (Dries007) have recently taken over as main developer and server admin. This involved moving servers to reduce cost. It's likely there will be some more downtime in the future but most  things should be sorted by now. This forum is in dire need of replacement as the software is quite old and can't be easily updated. If you wish to discuss or stay updated, join our discord: https://invite.gg/terrafirmacraft. The forum will remain available to read, but will be locked in the future, when a new system is setup. The forum and wiki are now ad free. If you'd like to contribute to keeping it that way, you can do so via paypal or patreon.

Description: I was playing just fine a few days ago. But now, when i open my singleplayer world, it loads for a bit and then when it says "Downloading world", minecraft just crashes. P.S: I was playing a custom modpack in the Technic Launcher, but I also tried to run the world in the Technofirmacraft modpack from FTB Launcher, but it crashed once again.

Your crash report shows that you have Optifine installed. Please uninstall it and provide a new crash report that is generated when Optifine is not installed.

Your save is corrupt. Restore from a backup. If you don't have a backup then you can try RegionFixer.

Thanks, I will try that.

Btw do you know why my world just corrupted 'himself'? Did I do something or it just happens randomly?

Corruption can just happen in MC. I've been lucky enough to never have a play world corrupt so I've never had to use region fixer. So unfortunately I can't offer much more help.

To be honest every time I had a corrupted region on my server I just ended up deleting the region. There are some tools that should be able to fix them, but I was never able to figure how to use it.

In our experience it's often a TFC contraption/block that's causing these problems in combination with the code not checking it's variables first. ArrayIndexOutOfBoundsExceptions are some of the easiest to prevent. Just check if a value exists before trying to use it. Alternatively one could use try ... catch mechanisms. This is the reason why Optifine is pretty much mandatory if you're playing on servers. It saves a ton of client crashes with bugged fruit trees because it uses more robust code.

At first we would load the affected chunk into MCEdit and remove the faulty block. But since it happens so often we opted for a similar solution as TonyLiberatto uses: if Optifine doesn't prevent client crashes try to delete likely culprits with world edit from a safe distance. If that doesn't work then just delete the chunk and start over.

Given that this is a single player world the World Edit approach may not work. The chunk needs to be loaded to be able to perform any action on it. And once the chunk is loaded the client is likely to crash. Perhaps if you're lucky you can load the chunk at the edge of far view distance and not crash. If that's the case then you could try using World Edit to delete the chunk. Otherwise try RegionFixer or MCEdit.

I tried RegionFixer and saw many tutorials, but in my computer things were different, i didnt have commands in my cmd such as scan, and i also dont understand much about programing. So i just started a new world. I am afraid that this might happen again...

Someone with more knowledge may correct me if wrong, but I always use the latest version of Forge. Even though TFC 0.79.922 was built using Forge 10.13.4.1558. Some of the mods you are using mayhave been built using newer Forge releases.

It's often a safe bet to use newer versions forge, but not always :)

Using an older version of Forge for any given mod is usually a bad idea. Newer versions of Forge often have fixes that don't affect mods that were build for an older version. But some times Forge changes things that mods rely on and then they can break. Only thing to do is trial and error to see what works. We've tested dozens of configurations for our servers and haven't found any issues with running newer versions of Forge. That being said, we do run the Forge version TFC was build for. Reason being that when we submit bugs we at least don't have to worry about that question.
