Ultimately a player is never forced to play their Flurry card. So, as long as the player knows how the mechanics interact beforehand, I don't see a problem with some conditions effecting the Flurry action (other than remembering which conditions effect it & which don't.)
This is true, but playing a Flurry card is supposed to be a good thing, not bad. I'm also curious what the official answer is, but my thinking is to keep things consistent and make the card useful all the time and speed things up as I could just see them confused about this one and it slowing things down or forgetting that it could have a bad effect like an extra Fatigue, just say it doesn't cause bad effects to repeat on their second turn. Basically just saying err on the side of the players here IMO.
