It worries me a bit that not many people seem to notice it so far, and the devs obviously didn't either. So it means that issue will probably never be patched (if it's even possible with the audio format they're using). Guess we'll have to live with it :/
On Gamefaqs there is a post that indicates they are compiling a list of known bugs/glitches and supposedly going to report it to Gung Ho. So hopefully it is something that will be addressed.
There is also something I've noticed. I'm not sure if it's a bug or not. But at least the question is with Justin's SP and using his Move. Right now he has 28 SP and I've used V-Slash a number of times, which has an SP cost of 14. But the cost has actually varied. Like one time I had full SP (28) and used V-Slash, and then had 16. Then another time I had 14 (after it correctly subtracted 14 for using V-Slash previously), but when using it a second time, I had 1 SP left. So it apparently only costed me 13 SP, instead.
I have not noticed this with Sue yet with her skills (Moves).
Has anyone else seen this?
Edit: Ok, this has gotten even more strange. The last combat where I only had 1 SP left with Justin, now he has 5 SP left all of a sudden. And now it's happened with Sue. I used her Rah Rah healing ability, which accurately left her with 4 SP left (she has 22 SP) and now after finishing the combat and running around Marna Road, she now has 5 SP.
What is going on?
2nd Edit: Ok, after the recent combat, both of their SP jumped by 5 SP. I am guessing it is part of the game and not a bug. I see they get "+1 SP" but can't tell 'when' they get that or what triggers it.
It's been a LONG time since I've played this game!
