Disconnecting a server when a certain mod requires a translation key

[viper-trick]

This is half a suggestion, half a problem. Some servers use mods that require the option for certain translation keys, so you need to add a config with the option to whitelist servers that I trust, or know don't use exploits.

with the mod: More Chests Variants (MCV)

This shouldn't happen. I will try fixing that issue in the next days.

Thank you, you are the best.

Update: It also happened to me in the mod Universal Graves

Another update, after further testing it seems that the problem was probably caused by ViaFabricPlus
(even though the client and server are in the same version)
After deleting Via, it shows the name of the translation key of the item instead of its normal name. (Which is probably what your mod is supposed to do?)

If the server doesn't know that mod (The mod doesn't leak itself) then it is normal. Do you have discord and have time for further testing that I can still try patching it?

Ok I guess I found the issue. This: https://github.com/NucleoidMC/Server-Translations/blob/main/api/src/main/java/xyz/nucleoid/server/translations/impl/language/SystemDelegatedLanguage.java can't be casted because in the accessor I use the class ClientLanguage and not the Language interface. I will try to patch that tomorrow.
