PetTracker is marked out of date for today's 8.0 pre-patch, and it has lots lua errors when I force it to load.

I hadn't realized how much I depend on this addon. It's become a significant part of my game.

Please take pity and release a working version!

I've left some errors in the comments section of the addon on curse.

Yes, when I've tried to use it, it made it so that swapping pets in the battle doesn't work. When I disabled it, I was able to swap pets again. But it is much harder for me to find pets that are upgrades.
