Board Game Arena

As in title.
I'm quite tilted - played the first card, but wasn't sure how will it play - it was hornblower. (pay 1 money to use hunting action, and/or pay 2 money to use set a trap action). I wasn't sure if it actually requires workers or not, so decided to check. I saw only option for hunting or to pass, I had only 1 free worker so assumed it requires worked to use. There was no button to restart/go back or anything. So I passed hoping there will be option at the end of the action. Well, there wasn't. So for my whole 3 worker turn I played 1 occupation card without any effect...

Anytime you reveal new information (like the card draw on 3 Viking action spaces) the move can’t be taken back. The Play 1-4 action is a 3 Viking action with a card draw, so if you choose to draw the card first, you can’t redo or undo your action.

What you say about not being able to undo an action when extra information has been revealed is true.However,in some games [ I encountered this in lost ruins of Arnak] you then do confusingly get an undo button but it doesn't work.
