There isn't actually a bug, but the way it works is misleading. They fill a set amount of health rather than the full size of your bar, and it will use more than one of them to fill as much as it can. You can restore these at save points if I recall, so it sort of balances out.

Err... Hi, I'm Sara. I'm a translator and a programmer. I work for Rockin' Android, Inc. I'm also doing a little other work these days as well. I guess I'm a musician, too, somehow. Not sure how that happened. If you really need to know more, you shouldn't be reading. You should be talking to me, learning about me. Knowing me.
