UPDATE 1:
Deployed a possible fix. Connect and let us know how you get on.

It appears the newest Anti-Hack files have broken a few things.
First off, people were getting their Humanity numbers doubled. (We had a few reports of this.)
Then the Anti-Hack author issued a new release but this has now broken various self-actions such as self-bloodbags, interacting with traders, bandaging and more.
You can read about it here:

But for now, we'll have to leave the server down until there's a new set of files. (They're usually pretty frequent and they only take me 10 minutes to implement.)
I doubt it'll be down for more than 24 hours. If we could roll-back, we would but it'd leave us vulnerable to certain cheats.
