I'm having trouble importing my world state

Some of the codex entries are bugged, iirc. Did you talk with the quartermaster yet? That's usually the best way to tell if everything has been set up correctly. You won't know about DA2 though until after getting to Skyhold and by then it's way too late.

It's also possible that while you think you have your WS selected in the keep, it's really importing the default state instead. Did you verify the date showing in the game when you selected it is the same date for the WS showing in the keep as ready for import?

Talking to Varric can also help to check that you have your own WS imported. That's how I realised that I only had the default the first time I played the game. Still if you are getting Anora as queen instead of Alistair that would seem to indicate you have got your WS and it is simply a case of bugged codices.

I know this may seem a silly question to ask but did you definitely export your World State at the Keep end as well as import it at the Game end? That was another mistake I made with a later game. I had changed the choices in the Keep but had forgotten to export it, so I was still getting the previous WS I had exported.
