This addon is fantastic, it was working perfectly when classic era originally released. I believe it was initially broken when the "tbc prepatch" was released.
I'm happy to learn how to fix it myself, if I could get some assistance. I have no experience with addons or, really, lua in general. Or if someone would take it upon themselves to update this addon, you'd have my thanks along with many other people's.

this is the most recent fork for the addon

this is the original addon that was working within classic era when I played with it.
Any advice here is good advice, open to any words on this at all.
