1. My unit was attacked by a spider with 'poison shot' and I couldn't identify anywhere in the UI that my unit was being poisoned each turn, this would make it hard to 'cure' if I had such a spell, which I would imagine there is one. Regardless, I should know which units are being affected by ailments.
2. I lost two units in combat but the results screen at the end of the battle displayed I had only lost 1 unit. The reason I suspect, is I lost the last unit on the last turn of the battle, so maybe it didn't count on that results screen? Anyway, the game did accurately show I had lost two units when the game returned me to the regular game map mode.
