I've already beaten the campaign but now she is stuck in a mission briefing conversation after which I can't talk to her anymore.
Also it seems that I can't progress with the Season 1 story because her "!" won't disappear and after restarting the game she would only do the same briefing and it is not possible anymore to talk to her or use her shop.
