It seems like this no longer works with the most recent version of Titan Panel. Any chance of it getting updated to work? I find this reagent tracker to be exceptionally valuable.

Hey mate, glad you find it useful! I'm not playing Wow any more so don't have an active sub, haven't been keeping track of what's changed and updating this add-on.

I'll take a look in the coming days/weeks and see if it's a simple task getting it to work with the new Titan panel, but I can't make any guarantees.
