Computer "Mad" crashes when I'm attacking

[heloirf]

It's happening very frequently in the most recent updates, when I'm playing against the computer (Mad mode) the game crashes when I'm attacking. One of the AIs does not pass priority.

"Declare Attackers - Waiting for Computer 4"

I'm using Skill 1 to make AI decisions faster, but it still crashes. Game Type Commander Free for All

Are you talking about server crash (errors like "card xxx not found") or simple game freeze?

On server crash you can try to increase server memory usage from launcher - settings - java options - server - find and change -Xmx1000m to -Xmx2000m or like that (it's increase memory from 1000 MB to 2000 MB.

On game freeze report cards list or battlefield screenshot here. Also some error or game logs can be useful.

Have a similar issue, not a crash or freeze but the AI will hang and refuse to assign a blocker, requiring a restart. Glissa Sunslayer reliably causes it.

+1 here...

Game has been freezing/crashing a lot more frequently with new update.

Freezing happens during combat phase, one of the bots never passes priority and the game can't be continued. Have seen it happening a least a dozen of times since the upgrade.

+1 Happens for me as well. Happens relatively reliably when I attack with [[Wolverine, Best There Is]]. I don't see anything unusual in my client or sever console when it occurs.

The computer has no untapped lands, and having built that deck it's using, it shouldn't have any mana-free actions to attempt. Interesting to note that attacking won't always cause this, but I honestly haven't been able to determine when it will vs. won't. Sometimes it refuses to take actions when it's lethal damage, sometimes it goes through just fine. It could be an issue with double blockers? That seems to be a common trend across these screenshots atleast. Hope this helps, and thanks for your hard work, I really enjoy xmage.

{1}{R}{G}

2/2
Unrivaled Lethality — Double all damage Wolverine would deal.
At the beginning of each end step, if Wolverine dealt damage to another creature this turn, put a +1/+1 counter on him.
{1}{G}: Regenerate Wolverine. (The next time he would be destroyed this turn, instead tap him, remove him from combat, and heal all damage on him.)
