Can't command companions to perform special actions

Hi,

not sure what happened, but ever since I got the dagger that was supposed to help me perform special actions even without companions in my current party, those actions are not working even when I have them in party.

Bellara isn't activating any crystals, no matter whether she's in my active party or not (tried those in the Crossroads). And I can't get Lucanis to open the bridge in his recruitment mission. Which basically makes me stuck on the quest without any possibility to progress further.

I press tab, it opens menu, it says Lucanis can use this, I select it - it lights up with checkmark. I exit the menu. And that's it. Nothing happens, Lucanis doesn't proceed to do anything.

Already tried to load earlier saves, quit the game to desktop. Still the same issue.

Any ideas what to do?

Thank you.
