I played metalmeld when only one artifact was destroyed and it equipped an artifact that was not destroyed.

Also, when in the card collection screen, sometimes clicking on cards does not select it and you have to exit and enter the collection screen to resolve it.
Finally, I opened a card back from a crate, but it is not unlocked in the card collection screen.
I use browser version.
