When I type /carpet chainStone in chat it just says that it doesn't recognize the command, was the command removed?

What version of Carpet Mod and Minecraft are you using?

1.16.3 and I'm using the 1.16.4 version of carpet mod since gnembon said it should work okay

It says that the entire command doesn't exist? Or just the rule?

If it's the latest, then you must be running an old version of Carpet, get the latest release here (the one that says for 1.16.4, since you are using 1.16.x).

However, if it's the first one, then either:

• Carpet didn't load: Check you are running Fabric Loader in the server (client if singleplayer) and that Carpet is in your mods folder
• You have locked your configuration file: Check that the carpet.conf file in your world folder doesn't have locked as the first line

After checking those, the /carpet chainStone command should show the information about that rule and allow you to toggle it.

im using the 1.16.3 version of Minecraft and all the other commands work just fine, you may have misunderstood me I downloaded the latest version of carpet mod that works for 1.16.3

Almost sure you are using 1.4.12 (the release just before chainStone was added, explicitly marked for 1.16.3 since .4 didn't exist yet), but feel free to think you are using the latest version even when you aren't.

1.4.17 (or at least 1.4.13, the first release with chainstone, or 1.4.15, last that explicitly says that should work) doesn't specify 1.16.3 in the name, but should be compatible with it according to the patch notes.

If you are really not using one of those Carpet versions, please specify the version, since "latest" is a broad term.

How broad? Iatest means 1.4.17. No vagueness involved...

"Latest" can refer to:

• Latest commit (at date...) (for branch...)
• Latest release (at date...)
• Latest release built against (version...) (at date...)
• Latest release that says should be compatible with (version...) (at date...)
• Latest release that should be compatible with (version...) (at date...)
• Latest release for (version...) (at date...)
• Latest version published to Curseforge (at date...) (they still have 1.4.12 lol)
• And more...
• EDIT: Latest commit from PR (pr...) (at date...)

That's why in some issue templates they tell you latest is not a version.

i checked in my mod file and carpet is 1.14.12 i will try a newer version if the problem gets solved i will close this issue, thanks.

but will the settings in the carpet.conf reset if I download a newer version?

No they won't, configs are always kept between versions, since they use the same format.
