this happened to me as well. I couldn't cast it for multiple turns. Ended up losing the game. I even tried to manually tap the mana, which left me nearly tapped out for an entire turn. Even force closed the game mid cast to try and correct.

I also experienced this, at 2 life. Same as others, got a surveil text and the last pip in the phyrexian mana was gray and unmovable. Everything on the screen was unable to be interacted with except view battlefield and esc menu.

Mi è capitato lo stesso in draft. Ero a due punti vita e mentre provavo a castare k'rrik si è creato il bug "Sorveglia".

Same happened to me, twice. One of those times it caused me to lose a game I would have otherwise won, during a quick draft even. Compensation would be nice.
One time I was at 2 life when it happened. The other time I was at 3 life. I play on PC.

Attached screenshot and log.

I was unable to complete casting the card but I was able to concede the game.

Same for me it says somthing about Suvail sadly it was in my draft also wasent able to close the window and was stuck untli all my time was run out basicli skipping my turn
on PC and also 2 life. Also so compensation for the Darft losse wold be nice

Happened to me too.

This happened for me as well and I have to Concede the game. Attached is my log, playing on a PC

Had a very similar situation occur with K'rrik in Sealed. Was also at 2 life but had plenty of lands. The interface header said "Surveil" and none of the buttons would let me cast the card or cancel. Had to concede the game.
