[BUG] empty category blocks command execution

[markusobi0]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

If you create a new category and do not place it directly in a panel or do not create a ticket directly via /new, some commands such as /close or /move can no longer be executed.

Expected Behavior

An empty category should not affect or prevent ticket handling

Steps To Reproduce

1. Create an empty Category
2. Create in another Category a Ticket
3. Try to move or close the Ticket via /move or /close

Environment

- OS: Ubuntu 20.04.5 LTS
- Node: Node.js v18.17.1
- NPM: Not known
- Bot: 4.0.10

Anything else?

A restart of the bot container doesn't help

Workaround: Create a Testticket via /new in the new empty category and close it.
