delete this config file

iirc the function you describe does never exists for the server console. Do you host the server on your pc?

Valhelsia Structures needs to update for the new Forge version. If you want to use the Mod you need to downgrade to 39.0.44.

this is a file on your pc, you can use https://imgur.com/ to post screenshots

did you install the required Mod

Minecraft 1.16 requires java 8-15, you currently using java 17, downgrade your java to 8 and the problem should be fixed. Note: do not use java 8 version 321

I also noticed that I wanted to change my answer, but thanks for the correction😅, but I also realized that this could get a bit complicated, depends on how much you want to change the logic the global_loot_modifiers.json is required iirc

the thread you linked is from 2013, the source code from mojang has changed a lot and forge use since 1.17 (1.16.5) mojang (offical) mappings, this means all classes, methods and fields have the same name as mojang source code. that means for you that this old thread is useless this is a documentation about forge, only important things are explained there, so not usage of each class, method and field if you want a javadoc for the minecraft source code you can use Parchment

do this

modified config: when you change any value from it's default to a custom one

You can't You can't the json file is required

Error in flywheel, make sure the mod is up to date. If you already use the latest version of the mod report the bug to the mod author

post debug log from server and client

create your own thread and answer the following question there, do you have java installed?

no, only the mod author can fix this

post full debug log and launcher log

You have to create your own logic, since vanilla only check if it's the Fortune Enchantment (they don't use a instanceof check). For a custom logic I would recommend you to use Global Loot Modifier

server: server directory/logs/debug.log client: .minecraft/logs/debug.log

No, downgrade to java 8 version 320, since the latest version (321) is currently not supported

you find the debug log in .minecraft/logs/debug.log

download a older version of java 8 and then use the full path to this java installation in your .bat file

show the run file you are using

do you run the forge server?

read the javadoc of OverlayRegistry.registerOverlayBelow

post the debug log please
