A great deal of bugs have been fixed over the past few months; the change log will be updated in the next server patch. I
think all bugs mentioned in this thread have either been fixed or are listed below, so this should serve as a good marker for new bug reports. Here are the known (and undisputed) bugs which remain:
Throne of the Golden Hall lets you exert the Man about to take a wound, but the card says "exert another".
Seeking New Foes forces the Shadow player to do Lurkers last, but this restriction applies only to the FP player.
Cast from the Hall seems to function the way it did pre-errata
Halls of My Home is a forced discard, rather than an optional one (thanks to Dictionary for these)
Orkish Sneak doesn't always work as intended
Final Cry can't be used if The Balrog dies as a result of the skirmish
The Witch-king, Deathless Lord does nothing if all companions and allies are exhausted
Nine-Fingered Frodo and the Ring of Doom does nothing if there are no burdens and only one threat
Drawn to Its Power (and similar effects) adds a burden even if it was The Ring-bearer who was killed
Dwarven Axe discards one card per minion rather than one card per player
Discarding from Watcher in the Water doesn't prevent certain effects when minions are played (such as
Moria Scout and
Fat One Wants It)
Allies can transfer items to other allies with different home sites (a patch for this one has been made, courtesy of Tbiesty)
Game crashes when replacing a controlled site
