Garen

(1) On several occasions, when using a blessing to add dice/die to a check, it incorrectly REPLACES my die instead of adding a die. For example, if I'm rolling a d6 on a non-combat dexterity check and use Blessing of Calistra, my d6 goes away and instead I get 2 d4. This has happened with Blessing of Sarenrae and Blessing of Shelyn as well. I haven't used blessings for every case where I would get 2 dice, but I know those for sure. (2) I've used Seoni's arcane blast ability for some fights. I discard a card to activate it, but if I cancel it, it does not return the discarded card to my hand! (3) Sometimes when I want to use a weapon, by either reveal or recharge, those tabs don't appear. I usually just tap the screen where I think they may be and the effect still works, but this is an issue, nonetheless. (4) In the fight with Mokmurian, several of my characters have defeated him in the first round of combat, but instead of proceeding to the second round, my turn simply ends!! He isn't shuffled back in the deck, he just remains on the top of the location deck. What's going on here?
