Treasury: Table Index Is Nil

Open up the lua in the directory and see what’s going on

Windower>Addons>Treasury>Treasury.lua

Though keep in mind, your issue is probably your data xml

Which is ..\Treasury\data\settings.xml

That error means your addon is failing to create a table.

You says your settings are being reseted. That kinda makes sense, your table isnt being loaded then your program is trying to get an element from a table that doesnt exist.

You can try to print after the place your settings are being loaded to see if the table is actually being created. In the worst case and your program is failing to create/load your table, you could just create manually your own table inside the program till the author fix the addon.

the settings.xml is corrupted, probably by an item in your list that changed name, it would help if you posted it (link to a pastebin or something) or try the windower disccord under v4 support (probably faster)
