Edit: After watching the replay, it seems that the skirmish actually resolved on my opponent's end, but I never saw that part. What happened on my end was I started the skirmish, hit Pass, and then the game froze. When I hit Refresh, all of the cards and game data had disappeared.
The only way I can think of finding the problem, is if in Chrome browser, after hitting the refresh in a broken game, you send me the contents of the JavaScript console (Tools->JavaScript console), or screenshot the output in the console.
Sure, next time this happens, I'll do that.
More details about the
Relentless Warg thing:
Two separate games, I've used the
Relentless Warg. In the first game, when I played it, I spotted a Man, and my opponent assigned the
warg's bearer to a Man. As soon as that skirmish started, the strength values of both sides got blanked, and neither of us could perform any actions.
In the second game, I spotted a Hobbit with the
warg's text, and then my opponent assigned it to a Man. The same thing happened when the
warg's bearer's skirmish started.
