Bug Description

1.21.11 worked just fine, however 26.1.2 seems to have changed something with having to do with multiworld plugins like worlds, myworlds or multiverse. Default worlds work just fine with worldguard. For example when removing all multiworld plugins' worlds, worldguard loads up perfectly. Thank you to whoever is looking at this! I appreciate the help

Error occurred while enabling WorldGuard v7.0.16+2355-f7fded2 (Is it up to date?)
java.nio.file.InvalidPathException: Illegal char <:> at index 32: plugins\WorldGuard\worlds\worlds:resource\config.yml

All the steps I have tried for the past 3 hours.

1. Loading a new world with a multiverse plugin (I used worlds https://modrinth.com/plugin/worlds-1) does cause all sorts of errors if you try to do it mid-game and crashes that world created.
2. Launching the server without any worlds loaded other than the main three worlds does work.
3. Going to plugins\WorldGuard\worlds\worlds:resource\config.yml and changing it to false. (Also does not matter when making that config completely blank when trying to follow the instruction that says: "if you don't put anything in this file, then the settings will be inherited from the main configuration file.")
4. I have only tested this on Windows and I have been reading that this may not happen on linux as windows does not like ":" in folder names etc.
5. Gone to the worlds discord and confirmed that it is a worldguard issue. Also confirmed it myself when completely removing worldguard and worlds created and loaded and played perfectly fine.
6. Creating a fresh server with only the necessary plugins causing these issues (Worldguard, WorldEdit, Worlds)

Expected Behavior

The behavior expected is to load worlds without the config error listed above. Tested many times on a 1.21.11 server and no errors were found. Worlds loaded and unloaded just fine without any worldguard errors.

Reproduction Steps

1. Install a multiverse plugin (https://modrinth.com/plugin/worlds-1)
2. Install WorldGuard and WorldEdit
3. Launch the server. It will work just fine until you do /world create anyworldname
4. Being in that world for 5 seconds will completely overload the server and bring MSPT to the millions
5. Close the server and relaunch. Worldguard will post the same error I posted in the bug description
6. Uninstall worldguard or delete the custom world and things will work just fine again

What world plugin are you using? from a chat in discord, this seemed to be caused by oddities in the actual world plugin used. From testing it did not seem there was an alternative for WG here, as we need to create folders that are user recognisable

I use: https://modrinth.com/plugin/worlds-1

[me4502]

From the investigations the other day, it seemed that specific plugin is adding worlds with names that instead look like keys, and therefore cannot be used as folders (the point of a name). As WG needs both reproducibility of world folder names (getting the world from the folder name), and clarity to users (eg, we can't use UUIDs as then people won't know what the folders represent), what that plugin is doing seems incompatible with what a world name is meant to represent.

I'm not really sure what kind of workaround we can really add here for plugins that insist on adding worlds with names that aren't valid for folders. I'm honestly surprised that Paper even allows it

Well, it seems I'll have to wait for a fix from Worlds' side instead of WorldGuard, thank you.
