Steps to reproduce:
1. Cast Urgent Necropsy.
2. Choose the following three targets:
- a Treasure token (artifact)
- a Cadet Token (creature)
- Chandra, Torch of Defiance (planeswalker)
The total mana value of the targets is 4, so the cost is collect evidence 4.
3. The game moves to the screen for choosing cards to exile from my graveyard.
My graveyard had enough cards to pay the cost:
two cards with mana value 1, two cards with mana value 2, and three cards with mana value 3.

Actual result:
- Clicking the cards in my graveyard does nothing. They are not selected, and the mana value counter does not increase.
- Pressing Cancel does not return me to the previous screen.
- I could not take any other action, so the timer ran out. The only options were to lose by timeout or to concede.

Expected result:
- I should be able to select cards from my graveyard with total mana value 4 or greater and finish casting the spell.
- Or, at least, Cancel should return me to the previous step.

Notes:
- I did not take screenshots or video because I did not expect the bug.
