So, this may have been pointed out already, but in the coin flip scene with Setzer Edgar and Celes stay red even after Setzer makes the offer of help for Celes as his mistress. Obviously they turn red in embarrassment when he suggests it....but never turn back until after the scene. I don't remember if this was the case in apst versions, but it just seemed odd here.
Also, I may have missed this in the changelog but is Locke supposed to get free turns when stealing? Every time he successfully steals something, he immediately gets another action--which is great for farming steals, but I don't know if you intended it or not.
I'm just about at Thamasa, so still a long way to go, but 1.9 has been just as good as 1.7 (the last version I played).
