Sorry, just a broad comment.

There are a lot of missing recipes in Classic Era.

It's every zone I'm finding 2-3 NPCs that sell recipes, and not seeing the recipes showing up as missing.

Is there a way to revert the Classic Era data back to pre SoD? Dunno if that's causing it, but it's really not accurate for Classic Era data any more. Shame, it used to be really tight.

I checked, I am only checking for my character.

Here's another example. These don't show up in the tracker, or on the tooltip.

But there are a bunch of recipes for me from this NPC in Feralas.

Tracker shows a lot of stuff, just not cooking recipes.

And, as you can see Account-mode is off.

Those recipes are present in our code.

Can you hover over two of the recipes and then screenshot their tooltips? Let say for Mightfish Steak and Hot Wolf Ribs.

I am confused. Here it says that you have that recipe already known (Gogohunter, character from your screenshots)

Only by looking at this, the "4/4 100%" message works as intended as you have the recipes learned.

But here says Unlearned and shows that you have Cooking Skill of 285

And here it says "Requires cooking 275" in red, which should not be red if you have Cooking Skill of 285

Do you have cooking on that character or not? What skill level is it? Do you have a Gogohunter on another realm?

Let me check the NPC ID, bit of a flight. Back in a few minutes.

IDs seem to match.

What can I do to help with this?

Well, correct. Your character might not have them, but your filters since you have Account Wide checked next to Recipes, ATT assumes that you only care about having a recipe learned on any character once on your account to consider it collected. If you want to collect a recipe on all of your characters, buy multiple copies of the recipe and mail it to whoever doesn't show up in the "Known By" section of the tooltip. If your current character doesn't know the recipe, it should also appear in the Vendor list as well as on the tooltip of the vendor you are looking at with Account Wide next to Recipes turned off.

Well, for one we didn't remove anything that was present for Classic Era. In your screenshot you see Blue Completion text on those vendors in their tooltips. This means that according to your filters, your character has completed everything found on that vendor. If you have Account Wide checked next to Recipes, that would explain why ATT is treating the vendor as completed if any of your characters have the recipes learned. When moving about the game, sometimes not playing in Account Mode or using the Account Wide checkmarks to the left of each Thing on the list is the way to go.

My character didn't have those recipes. Not all of them.

Like see the top screenshot, things are red if I can't use them or if I already know them. (From another add-on.)

So if they show up as default color, it means I haven't learned them yet on the toon I was on.

I'll work on some other examples, I learn things as soon as I find them.

And I'll review my filter settings. Thanks for that suggestion!

That's a bug with Recipe Master, good pick up though. (=

Hunter knows the skill, but Recipe Master didn't know hunter knew it. I was playing with the code on that add-on and likely had it off, or didn't open Cooking since messing with the code there. You can ignore that.

I'm still seeing an issue with Cooking Recipes in ATT.

They don't seem to be showing for NPCs. Other recipes show up in the tracker, and NPC tooltip. Just not Cooking Recipes.
