Anyone else hit this issue?

When playing as Ellen. After reprogramming the Anubis statue's chip to accept Me as your Master, sucker - there isn't a conversation option to get the passcode.

A glitch or am i doing something wrong?

Started the game again and played though to the same point to see if it was a glitch. Nothing changed.

I inscribed to make Humanity Anubis's new master and the possibility to ask for the code did appear.
Try that.

I had trouble with this too. Try interacting with the sarcophagus again and then talk to the Anubis.

Thanks for your responses to this.

It was the sarcophagus.
Not sure which action you have to execute on it, but went through them all and the code option came up.

Thanks a lot folks, much appreciated!

I think looking at the sarcophagus is the action you have to perform here to trigger the conversation option for the password.
