PathOutsideElementException on new install.

[ActivexDiamond]

OS: ArchLinux
Kernel Version: 6.17.9-arch1-1
Minecraft Version: 1.21.11
Launcher: PrismLauncher
Launcher Version: 9.4
Thanos Version: Latest
World Used: I tried multiple. A large one, a simple superflat one, etc... All returned the same error.

I installed Thanos using the follow command:

composer global require aternos/thanos

This placed it inside ~/.config/composer, I then copied a simple test world there and tried the following:

cd ~/.config/composer
./vendor/aternos/thanos/thanos.php "Trading Test/" out/

A blank out file is created, and the following error is thrown:

~/.config/composer[255]>./vendor/aternos/thanos/thanos.php Trading\ Test/ out/

Could you send me a world you are experiencing this issue with?
You can email me a download link to kurt@aternos.org if you don't want to share it publicly.

Does your world folder contain any symbolic links?

That's the odd thing, it does not.

I was initially just passing thanks the full path to my instance's saves (which also includes no symlinks). But after seeing that error, I tried copying directly (as mentioned in my issue). Still no change.

It's also worth mentioning that I tried renaming the world's directory to a name that does not include spaces. Same result.

Here are the two worlds I used. "Trading Abuse" is somewhat well explored. "Trading Test" is a simple flatworld with very little in it. Both we created and are being played on 1.21.11.

Sorry for the late reply; I was on vacation, and then there was a lot going on regarding Hytale.
I'm able to reproduce the issue, and I assume it has to do with placing the world in the .config/composer folder, although I'm not sure how exactly that would be an issue.
If you want to use Thanos as a standalone app, I would recommend cloning the repository for now instead of using composer global install. I'll look into how to make it work with composer global install.
