I Chopped at two Forest Spiders. One of them Jumped Back out of range, but they both still took damage. I did not mind.
Jump back doesn't work if there are blocked terrain behind, despite successful roll... I did not mind either.
Same sort of thing happened with a different card but I was paying more attention. I swung a Chop. The first monkey played Monkey Flip and pushed me away. The other monkey still got hit. Since you say it does think about stuff after the move, I think it is just an art bug. How about the monkey who took damage was actually the first one attacked, but he didn't play the hit effect until after the second one was done pushing me so it only looked wrong. Italics doesn't really work there, but yeah.
The power of ASCII compels you! T = Thorfin Dragonhammer, last Battlerager of his clan 1 = Effing monkey 2 = Other effing monkey . = Empty square .. .T 12 .. T : Imma Chop you! 2 : OOK! (Nuh uh! I have Cheese Block +2!) .T .. 1. .2 * Monkey 1 plays hit effect. * 1: Ook? (Wtf! Why'd I get hit? You are out of range!) The confusing part was me thinking "Hmm... maybe I hit monkey 1 first before 2 pushed me. So only the hit effect timing was wrong. And the monkeys were in separate groups so Monkey 1 didn't have a Flip card."
