I have a character assigned to a Major Adventure, but the button on the right hand side says Assign when it should say Recall. Can't upload screenies yet, but I have one). Save/Load corrects this.

This is still an issue. According to another thread it's been on bug tracker since July at least. I can upload a save for reproducing it, if you don't have one already.

Hello Erickei,

 

Thanks for bringing this to our attention. Fortunately we are aware of the issue and working on a fix. Clicking on the button will Recall your character, so it is functioning correctly, but the UI is not. 

 

Thank you for your support.
