As far as Palantir, you can use it multiple times in a turn to see a card and put it on top of the opponents deck, on the program it shows you the first card but it does not show you each additional card that you put on top of their deck. Hope that helps, let me know if you need more info.
Ahh, I think the problem is, that using Palanthir requires removing (1) twilight. The ability was not checking if there is twilight, before it shown it's usable, but removing of the twilight was failing, therefore the Palanthir was not doing anything. This is fixed - you will not be able to activate Palanthir if there isn't at least 1 twilight in pool.
