Forge should be completely compatible with vanilla clients, and vanilla servers. The issue seems to be that your old entities contain a Attribute at an ID that the vanilla client doesnt like. As I asked on reddit, you should share your old save file, as well as the mod list the server was using before and after the update. Give us information to debug and we could probably find the issue.

Honestly, the answer should be no. It doesn't give you an unfair advantage. Its like using a piece of paper to check your math. Plus its not like you can 'cheat' in your own world.

This is not a Fabric forum, this is for Forge mods. And typically we don't do commissions/requests.

Server configs are automatically synced to the client. The mod configs are automatically loaded from disc when the files are changed. There is a bunch of ModConfigEvents for whenever the respective event happens. However, you could probably just get away with just reading the *Value field you make when creating your config.

There typically isnt a place to commission mods. Mods are made by hobbyist programmers in their spair time. You could try some general minecraft modding discords, but I dont have any to recommend.

minecraftLibrary is required for dev time for it to load. jarJar should be enough for runtime. be sure you're running the latest forge. And make sure you post your debug log.

Unfortunately, it seems that Invision has decided that everything is locked down and no longer customizable. Their attitude to anyone who wants to edit anything is 'Just accept it we know best and screw you for even insinuating that you want to customize your own site' So there isn't much we can do about the layout of actual features. Best bet for the editor is that psudo markdown works, so typing ` around words make code blocks. Only options is to start writing bespoke modifications to the forum's php code itself, which I really don't want to do. I would of stayed on v4 but the version of PHP that it supports is going EOL and Invision has stated they have no intentions of upgrading it. They also removed the central community for finding plugins/community addons. Overall it is my feeling that they are intentionally trying to kill off self-hosting communities by removing features and locking things down, in an effort to force everyone into using their paid hosting services. My HOPE is that someone in the overall forum community will write an exporter for Invision to something like SMF. Which is what we were originally on before old team members decided enterprise software is better.

Thats not something Forge will add, but there are events for when sounds are played, and pretty sure you have the ability to adjust the volumes in that event.

We are not fabric and do not support it. So best option is to ask them

The networking has been far simplified in 1.20.5+ The docs could be old, as Ash has said feel free to submit a PR updating the community docs. However the only real up-to-date reference would be the code itself. So your best bet is to just read the code and give it want it wants.

We have an event for an Entity being struck by lighting, but doesn't look like we have one for Blocks. And unfortunately, looking at it, the LightingBolt entity doesn't have any context on why it was registered, so you wouldn't be able to get the source context. What are you trying to accomplish with this event?

Honestly, the forums are a back burner thing. Not many people use it. Best option is discord. I know that I haven't looked at the forums for more then admin tasks in quite a while. You're also best off not following tutorials which give you code. Knowing programming and reading the MC/Forge code yourself would be the best way to go.

The site is dumb and doesn't like upper cases.

You just need to run the updated installer like if you were installing a new server. You can overwrite an existing install with a new version.
