Board Game Arena

Hi,
I have noticed while playing the game in Arena that there is no ruins card in the deck, which is weird because the rules https://cdn.1j1ju.com/medias/18/60/72-c ... lebook.pdf say at page 14:

Always include the ruins cards, no matter which set of explore
cards is used

.
I have checked the options available when you setup a game. They are Default and Base. For this arena season the option is Default.

I think the ruins should be always included in the game, as written in the rules.
However I have nothing against an option to remove them if someone likes it. But in this case, the options should be Yes or No.

What do you think?

Kind regards,

Cartographers: Heroes has no ruins cards in the box. Since Arena is now playing Cartographers: Heroes and Ruins were not explicitly included in the game options: Ruïnes are not included.
