Additional context
Happens in every server regardless of anything.

is your bot in multiple servers? Have you changed the GUILD_ID recently?

[ElijahPepe]

1. I just created it.
2. I didn't change the GUILD_ID.

[StephenDaDev]

@ElijahPepe Is this issue still happening with the latest update?

[gabefraser]

I am experiencing the same issue. I haven't changed the GUILD_ID and I am using the latest version of repository.

Hey, try running ?setup , if this does not work try ?config set main_category_id 3672362836872387 ( replace the numbers with the modmail-catagory id )
And if none of those work your modmail-catagory most likely run out of channel space. ( the max allowed channels in 1 catagory is 50 )
