EDIT: So it seems that Hooks are currently disabled due to patcher issues ah :( Need to wait for another oxide update or plugin update?

List of errors i am seeing in the rcon:

as well as this when a player joins:

Halp!

Getting the same thing, just tagging along in the thread hoping for a fix

I am not having any problems with the plugin after yesterdays and todays (small) patch,

(23:13:11) | Protocol: 2180.180.1

Build Date: 07/06/2019 09:54:35

Unity Version: 2019.1.4f1

Changeset: 37098

Branch: release

(23:13:33) | Oxide.Rust Version: 2.0.4249

This error in the first post means that a message was not formatted right, it doesn't have anything to do with any hooks and no hooks that this plugin uses are disabled either. A hook is something that gets called to trigger code, this is clearly being triggered as you see an error.

What the error is saying though is that one of your values configured/used is not correct and not as expected, and it can't format the message using that value. Looking at it in more detail, you can see that it has to do with your panel configuration settings, so I'd suggest checking those to make sure they are valid and follow the default format of the config file.
