[TTT] Karma do not go under 1000

Im hosting a TTT-Server and have problems with the Karma-System. It does not go under 1000.
Thank you!

What addons do you have? Something is overriding the Karma system.

I have a lot of addons.

Do you know, which files are the karma system?

Knowing the files of the karma system is no issue.

Something you added recently is interfering with the database.

Are you using a mysql for Karma?

No, i dont use mysql for karma.

Edit: Ok, ive fixed the problem. I just added the config settings for karma from: http://ttt.badking.net/config-and-commands/convars#TOC-Preparation-and-post-round to the server.cfg and now it works!
