1.   Attempt to cast K'rrik of Yawgmoth 
   

2.   Platform: PC
   

3.   While casting the spell, the interface for selecting between Phyrexian and black mana costs says "Surveil" along with instructions for how surveil cards. Also, both the "Done" and "Cancel" buttons are unable to be pressed; the interface was unable to be closed and no game actions were able to be taken from then on. Once my turn timed out, the game was able to continue as normal (although I did not attempt to cast K'rrik, Son of Yawgmoth again)
   

4.   K'rrik should be able to be cast as any other spell. The Phyrexian mana interface should work as expected.
   

5.   Screenshot is attached, along with most recent log. 
   

This was during a quick draft Modern Horizons 3 game, which I then lost due to "skipping" my turn and not casting a spell. I would like compensation for this.
