Cards lands in wrong Building Pile

[georgiee]

1. Have a card 1 in your possession.
2. Throw it on an existing building pile (where it can't placed)

Expected Behaviour

Throw an exception ERROR Error: The card 1 can't be placed in the selected building pile

Current Behaviour

It will be placed on the next possible building pile if any.

I guess that's a missing implementation in the Skip-Bo Core and it's still doing the automagic which was useful before having Drag & Drop to select a distinct card.
