No response

Which version of ATT?

Latest release

What build number of ATT?

4.2.1.0

What isn't working? What was supposed to happen?

The Error pops up since a few weeks (so not only with the latest release)
I only get it on my Horde Chars, when they are in the Dazar'alor "The Great Seal" zone, or anywhere in the Pyramid part of the zone.
Its not relevant, if they have done any quests. Even chars with zero quests done in BfA get the error.
Also disabled all other addons and the error still pops up.

Screenshot

Steps to reproduce the behavior.

Go to Dazar'alor with a Horde character (Great seal)
Logout
Login and wait

Are you experiencing any lua errors?

Anything else?

No response

Exact same thing happening to me in Zuldazar on a character I just log in to do mission table stuff.

US server

Was using 4.2.9a and getting it, upgraded to 4.2.10 and still getting it.

After Removing all "Allthethings.lua" files from WTF Folder, the error is gone for the moment.
If you need the files, i can extract them from my backup.

Experiencing the same issue whenever I login to a character in a BFA zone, Alliance or Horde.

Ok I've finally managed to repro this issue by allowing cost calculations on things that are already collected (meaning I never got the error myself since I've already collected whatever is causing the recursion loop)
So hopefully can figure out what it is and how to fix it
