My garlic was pretty ravaged, too. Most of the bulbs had split into cloves, but they then just stopped growing and so many of them are weeny. I've just dug them all up - clearly not going to grow any more - and minced the garlic to use. The onions were OK (next to the garlic) but the broad beans got rusty, too (on the other side of the lottie). Weird.
