Overall Grid is working great since the pre-patch. I updated to version 7.0.0.2-1 yesterday (the latest version as far as I can see) but I've got a small problem.

When we raid my raid leader likes to pop all the benched/offline people into group 8. Never been an issue before since I was able to hide group 8, but now Grid isn't allowing me to do this. I tried deleting Grid and all the dependent addons I have for it from my addons folder entirely and still had the same thing happening. Anyone else ran into this problem?

Just a shot in the dark incase anyone else here had the same issue and managed to come up with a solution (other than switching to a different raid frame addon). I know the prepatch literally just came out so maybe they're already working on a fix for it.
