So yea.. along with online issues people seem to be having (me included - cant get into a game at all).. and people saying their characters stats are getting erased whilst playing on different consoles (read - Ryans post).. Ive come across some bugs of my own.. Dunno if its simply just my 360 or if its happening to others but -

- I was trying out all the characters, and using magic whilst playing with the Red Knight (the lightning dude).. doesn't work! I see the lightning animation.. but it doesn't connect with the enemies. At first I thought I was just crap at the game, buh using the other Knights magic attacks works just fine.
- It doesn't seem to save after I get past the level `Flowery Gardens` (I think that's what it's called -.-"). So I got past the level, did a few more levels after that, I decide to quit and it said at the on the screen `Saving`, and when I come back, everything after `Flowery Gardens` is locked. I try it again (get past the level), quit whilst making sure it said `Saving` on the screen, went back and everything is locked again.

So anyone else having SP problems?

Those aren't bugs.
For the Red Knight you have to be RIGHT in line with your enemy or it will not connect.
For the Flowery Gardens, it won't save your progress until after you get past the chase scene because it saves in chunks.  Meaning it will save after you complete a certain group of levels and do that for certain levels that are related that way.
