Here are some things that I´ve found so far:
1C331 Ettenmoors - when using the site ability on
Moria Scout, he doesn´t exert.
1C133 Saruman´s Ambition - doesn´t work on
Orthanc Assassin(he doesn´t get any strength bonus)
1C121 Bred for Battle - doesn´t exert
Orthanc Assassin.
1U178 Goblin Runner - no twilight tokens are removed(probably had something to do with
1U350 Dimrill Dale not turning itself off, as, if I recall correctly, it worked on earlier sites)
Occasionally some card´s special ability doesn´t work(they are skipped). I don´t know if there´s something wrong with the cards themselves or if the auto-pass feature is bugged.
1C349 The Bridge of Khazad-dum - doesn´t let me choose to play the Balrog when I click the site.
1C179 Goblin Scavengers - isn´t playing a weapon from the discard pile, even though
Goblin Scimitar is in there.
1P365 Aragorn, King in Exile - skips the option of healing a companion with the Aragorn signet.
1R289 Frodo, Old Bilbo´s Heir - skips Hobbit ally healing(in this case
Bounder).
Deckbuilder:
When filtering to Fellowship Block/Isengard/Minions,
4C207 Uruk-hai Raiding Party appears amongst the cards.
It would be more convenient if the close-up window that pops up when you Shift-click a card could be at the size of the cards.
The size of
6U117 Meduseld thumbnail is odd compared to the rest.
