tried to get benefits of cards that care about collecting evidence, but the game won't let make an a legit choice of 0. At least let us cancel out of the option or disable 0 as option if you don't to use 0 as a value.

Had this one happen to me today in a Golden Sealed match. Opponent hit with Incinerator and an empty graveyard and timed out, at which point the game went a bit haywire with rapidly flashing triggers.

Closing and reopening Arena took me to the "Entering match" screen (displaying my Username and that of my opponent), but the program hung there. Reopened it again ~7 minutes later, and was still in the haywire triggers match screen, which I was able to concede from.

I have just encountered the same issue as well.

I'm also facing this issue right now. Can't play the game at all.

same thing

I tested this against Sparky, and the bug is specifically in the UI for selecting which cards to exile when the graveyard is empty.

1. Incinerator of the Guilty's ability begins to resolve.
2. The game prompts to take action or decline. Click to take action.
3. The game prompts to select the value of X. It won't even let you try to choose a value higher than the total of what's in the graveyard, but you can always choose 0.
4. When you choose 0, the game asks for confirmation because 0 is an unusual choice that is often a mistake.
5. After confirming 0, if your graveyard has at least one card in it, even if that card is a land (and thus has mana value 0):
-- a. The collect evidence card selection browser is shown.
-- b. You may select any number of cards, or leave it as is with no cards selected, not even a mana value 0 land.
-- c. The "Submit 0" button is enabled immediately.
-- d. Clicking "Submit 0" works correctly, though technically I didn't test whether this triggers "Whenever you collect evidence..." abilities.
6. After confirming 0, if your graveyard is completely empty, not even a single card in it:
-- a. The game either fails to show the graveyard browser or shows it empty, I'm not entirely sure which.
-- b. The "Submit 0" button is disabled. THIS IS THE BUG.
-- c. The only available action in the UI is to click the "Decline" button, which returns you to selecting the value of X.
-- d. There is no apparent action available in the UI to get out of this and let the game proceed.
-- e. However, pressing the Z keyboard shortcut for Undo can back out of selecting the value of X and return you to the "Take Action" vs "Decline" choice. Clicking "Decline" for that prompt lets the game proceed.

Same issue occuring on iOS.

Log for the issue

Same here - quite the client and tried to reconnect, but I'm now stuck forever on the Vs. screen

Same problem

Howdy! Just ran across this issue and lost a draft game because of it, thought I'd chip in my logs and video of the bug to hopefully make it a wee bit easier to track down so more gems aren't lost because of it! Seems the comment can't handle uploading the video clip, but here's a link to it on YouTube - link should take you to 29:30 and the relevant bit ends at 33:35 when I reopened the game after a forced close of the window and it registered a loss - https://www.youtube.com/watch?v=bTczRuEFDMc&t=1770s

I haven't tried testing it, but I would be curious if other triggered collect evidence abilities suffer from the same - the issue seems to me to be that Arena handles triggered "may" abilities by asking you to decide yes or no, and once the decision is made you aren't able to rescind the trigger - since in this case, the trigger requires you to pay a cost you might not be able to pay, you can't proceed and can't rescind your decision on the trigger, and so you get stuck. I am unclear if this also occurs when you have cards in your graveyard, but an insufficient amount to pay the cost.

Please fix this, getting stuck like this in a sealed game.....
