Searching and Karma disabled?

I noticed recently that my TTT server has had a few bugs. However, even after updating to the latest version they’ve persisted.

Bugs that I’ve noticed include corpses displaying their name even before being inspected,
Scoreboard moving dead players to Spectator the moment they die (before being searched, even)
Karma not appearing on scoreboard.

Obviously this isn’t right. Is this a known problem, or have I done something terribly stupid to break it?

Edit:

Turns out I’m bad at hosting. Updated Garrysmod and installed TTT from scratch again, and it’s all good.
