c.reload Rustcord
Failed compiling 'Rustcord.cs':
1. The type or namespace name 'Discord' does not exist in the namespace 'Oxide.Ext' (are you missing an assembly reference?) [CS0234]
(Rustcord 17 line 13)
2. The type or namespace name 'IDiscordPlugin' could not be found (are you missing a using directive or an assembly reference?) [CS0246]
(Rustcord 52 line 26)
3. The name 'DiscordExtHooks' does not exist in the current context [CS0103]
(Rustcord 21 line 276)
Couldn't find required plugin 'DiscordMessages' for 'DiscordServerMessages', retrying..

pretty sure you installed the cs into carbon/plugins instead of carbon/extensions where it belongs

yes it works now sory
