Hello there!
Just a nuisance that keeps happening to me.
When you are creating a character for DH in Demiplane, and you see the features or the cards, if you click to know more (or accidentally like I did) it goes to the card/ability page and you lose all progress on your character creation and have to start from scratch… If i could recommend a solution it would be that clicking those opens in a new tab.
Thank you!
