8 star coins left over after unlocking all paths in NSMB2..?

Okay.

So I just completed New Super Mario Bros 2 and as the title says I unlocked all paths on all the worlds. as far as I know I have every single star coin and moon coin collected (funny thing too, I had all the star coins but didn't get a popup about it after beating Bowser the first time around... )

So then I proceed to unlock the star world and every other path that I intentionally skipped through (mostly 1up houses and such), and I have eight star coins left to use. Where do these coins get used at?

You done fucked up bro.

Pretty much. I found my problem not too long ago, I missed a star coin in the world 3 fortress. After collecting it and of course getting through the fortress I promptly got the "you collected all star coins" message and went right to star world. There, an invincible star house was available for unlockage and I spent all my gold star coins.

So yeah, resolved my issue on my own, thread now locked.
