I was testing for some SFX bug I had somewhile ago, and then I noticed this bug, as soon as give an enemy BG SFX and place multiple on a screen, they like to be weird. Just check it out:

Also, that ZC doesn't use the continue location on start might be a bug, or just me forgetting it always was like that.
And to _L_ if he reads this, you will receive my quest file from me then (with huge protest), since I'm not able to track down the bug. A PM will explain it all soon.
