I seem to have hit a bug. When I go back to the Castra, taking Eve, it freezes after the first line of dialog as they greet Dina. I've tried reload an earlier save but no change :( Doesn't matter if let the dialogue run or try skip it, freezes and no sound or mouse.
I noticed Dina doesn't rejoin the party after saying to take her.

[EDIT] Found a solution. Watch the tablet a second time, then Dina responds and joins the party as should. Not sure why didn't work first time but I reloaded a save again to check and yep seem to need to watch the tablet twice :-/
